in which such employment is conducted) of each executive officer and director of
the Master Fund and Moon Capital Global Equity Offshore Fund Ltd., a Cayman
Islands limited company and the controlling person of the Master Fund (the
"Offshore Fund"), is set forth in Schedule A to this statement and is
incorporated herein by reference in its entirety. To the undersigned's
knowledge, all such persons are citizens of the United States unless otherwise
noted in Schedule A. During the last five years, none of the Reporting Persons
nor, to undersigned's knowledge, the Offshore Fund or any of Master Fund's or
Offshore Fund's executive officers or directors has (i) been convicted in a
criminal proceeding (excluding traffic violations or similar misdemeanors) or
(ii) been a party to a civil proceeding of a judicial or administrative body of
competent jurisdiction and as a result of such proceeding was or is subject to a
judgment, decree or final order enjoining future violations of, or prohibiting
or mandating activities subject to, federal or state securities laws or finding
any violation with respect to such laws.


Item 3. Source and Amount of Funds or Other Consideration.

         All of the funds used to purchase the ADSs described in this Schedule
13D came from investment funds under management of the Investment Manager.


Item 4. Purpose of Transaction.

         The Reporting Persons purchased their ADSs based on their belief that
the Common Stock underlying the ADSs at the time of purchase were substantially
undervalued and represented an attractive investment opportunity. The Reporting
Persons originally acquired their Gravity securities for investment purposes in
the ordinary course of business, and have previously reported their ownership of
ADSs on Schedule 13G. The Reporting Persons are filing this Schedule 13D to
reflect the formation of the Committee (as defined below) with the other members
of the Committee and to reflect the Committee's intention to take certain
actions as described in this Item 4.

         The Reporting Persons and the Ramius Entities have formed The Gravity
Committee for Fair Treatment of Minority Shareholders (the "Committee") to
protect the rights of minority shareholders of Gravity (Nasdaq: GRVY) and to
maximize the value of the Common Stock. The Committee believes that Gravity's
Board of Directors (the "Gravity Board")




CUSIP NO. 38911N107             SCHEDULE 13D                 Page 8 of 17 Pages


approved transactions that may have benefited Taizo Son and other entities
affiliated with Taizo Son or SOFTBANK Corp. ("SOFTBANK"), including GungHo
Online Entertainment ("GungHo") (JP: 3765), to the potential detriment of
Gravity's minority shareholders. Based on public filings, the Committee
believes that Taizo Son beneficially owns approximately 52.4% of Gravity's
Common Stock. In addition, based on public filings, the Committee believes that
Taizo Son owns approximately 82% of Asian Groove, Inc., which owns
approximately 32% of GungHo, and that SOFTBANK owns approximately 45% of
GungHo. SOFTBANK's President, Masayoshi Son, is Taizo Son's brother.

         In August 2005, according to public filings, an affiliate of Taizo Son,
with financing facilitated by Masayoshi Son or his affiliates, purchased a 52.4%
interest in Gravity from Mr. Jung Ryool Kim, Gravity's founder, and certain
members of his family (the "Controlling Purchase"). The purchase price of $24.70
per ADS represented a premium of over three times the then current share price.
According to GungHo's 2005 financial statements, substantially all of GungHo's
revenue was derived from products licensed from or sold and licensed to Gravity
with 82% of the revenue generated by the license from Gravity of the popular
online game Ragnarok, which license expires in August 2006. The Committee
believes that the $24.70 per ADS price paid by the Taizo Son affiliate in the
Controlling Purchase indicates that Ragnarok, among other things, is extremely
important to GungHo's business. The Committee also believes that changes in the
Gravity Board and management since the completion of the Controlling Purchase
may have been effected to protect GungHo's interests, to the potential detriment
of Gravity's minority shareholders.

         The Committee intends to examine, among other things, potential
conflicts of interest among members of the Gravity Board, several related party
transactions entered into between Gravity and entities affiliated with Taizo Son
or SOFTBANK, and the potential for future conflicts of interest in transactions
between Gravity and entities affiliated with Taizo Son or SOFTBANK.

         In particular, the Committee believes that Taizo Son and the Gravity
Board may have conflicts of interest and may not seek to maximize value for all
Gravity shareholders in upcoming negotiations for a renewal of the license for
Ragnarok, Gravity's main revenue driver. GungHo's license of Ragnarok expires in
August 2006. The Committee is also concerned that the Gravity Board may not
authorize management to solicit alternative bidders for the Ragnarok license to
create maximum value for Gravity shareholders.

         In order to maximize the value of Gravity's Common Stock and in order
to protect the rights of minority shareholders, the Committee, among other
things, may:


            o Hold discussions with holders of Common Stock in Korea, with the
              possible future inclusion of these holders in the Committee;
            o Consider converting all or a portion of their ADSs into Common
              Stock;
            o Seek to nominate independent members to the Gravity Board,
              potentially at a special Extraordinary General Meeting of
              Shareholders to monitor Gravity's negotiations of the Ragnarok
              license and to establish and oversee an auction





CUSIP NO. 38911N107             SCHEDULE 13D                 Page 9 of 17 Pages

              process to determine whether alternative parties might offer
              terms superior to those offered by GungHo;
            o Seek to negotiate with Taizo Son a resolution whereby Taizo Son or
              one of his affiliates offers to acquire all the Common Stock held
              by the minority shareholders; and/or
            o If necessary, commence litigation against Gravity, its management
              and/or the Gravity Board in Japan, Korea and/or in the United
              States.

         In the event that entities affiliated with Taizo Son or SOFTBANK offer
to buy the Common Stock of the minority shareholders, the Committee intends to
only entertain a proposal that offers fair value and is made available to all
Gravity minority shareholders. The Committee notes that, according to public
filings, an affiliate of Taizo Son, with financing facilitated by Masayoshi Son
or his affiliates, paid $24.70 per ADS in the Controlling Purchase. The
Committee believes that Gravity's prospects are strong and that Gravity has
significant potential for additional licensing revenues from games not yet
released, including, among others, Requiem and Ragnarok 2.

         The Committee has retained Hannuri Partners as legal counsel in Korea.
Certain members of the Committee have retained Schulte Roth & Zabel LLP and
Chadbourne & Parke LLP as legal counsel in the United States.

         Certain members of the Committee entered into the Sharing Agreement, as
more fully described in Item 6.

         The Reporting Persons may, alone or with others, communicate with or
pursue discussions with Gravity, and with other shareholders and other third
parties, with respect to the matters described above and potentially with
respect to other matters of concern with respect to the Reporting Persons'
investment in the ADSs.

         Except to the extent set forth above, or in any other Item hereof, the
Reporting Persons do not have any present plans or proposals that relate to or
would result in any of the matters set forth in Item 4 of Schedule 13D. However,
the Reporting Persons may, at any time and from time to time, review or
reconsider their position with respect to Gravity, and formulate (and modify)
plans or proposals with respect to any such matters. The Reporting Persons
intend to review their investment in Gravity on a continuing basis and may
engage in discussions with management, the Gravity Board, other shareholders of
Gravity and other relevant parties concerning the business, operations, board
composition, management, strategy and future plans of Gravity. Depending on
various factors including, without limitation, Gravity's financial position and
strategic direction, the outcome of the discussions and actions referenced in
this Item 4, actions taken by the Gravity Board, the price levels of the ADSs
and/or the Common Stock, availability of funds, subsequent developments
affecting Gravity, Gravity's business, other investment and business
opportunities available to the Reporting Persons, conditions in the securities
market, general economic and industry conditions and other factors that the
Reporting Persons may deem relevant from time to time, the Reporting Persons may
maintain their investment at current levels or may in the future take such
actions with respect to their investment in Gravity as they deem appropriate




CUSIP NO. 38911N107             SCHEDULE 13D                 Page 10 of 17 Pages


including, without limitation, purchasing additional ADSs and/or shares of
Common Stock or selling some or all of their ADSs and/or shares of Common Stock,
engaging in short selling of or any hedging or similar transactions with respect
to the ADS and/or Common Stock, or changing their intention with respect to any
and all matters referred to in this Item 4. Any acquisition or disposition of
ADSs and/or shares of Common Stock, or short sale or other hedging transaction
with respect to the ADSs and/or shares of Common Stock, by the Reporting Persons
may be effected through open market or privately negotiated transactions, or
otherwise.
