==================================================================================================================



(1)  The number of additional shares of Class A common stock, par value $0.001
     per share, of the registrant ("Holdco Class A common stock") being
     registered is based upon the sum of (i) the product obtained by multiplying
     (x) 41,300 shares of Class A common stock, par value $0.001 per share, of
     GameStop Corp. ("GameStop Class A common stock") estimated to be
     outstanding immediately prior to the GameStop merger by (y) the exchange
     ratio of 1.0, plus (ii) the product obtained by multiplying (a) 308,374
     shares of common stock, par value $0.01 per share, of Electronics Boutique
     Holdings Corp. ("EB common stock") estimated to be outstanding immediately
     prior to the EB merger, by (b) the exchange ratio of 0.78795. The
     Registrant previously registered 54,382,484 shares of Holdco Class A common
     stock and 29,901,662 shares of Class B common stock, par value $.001 per
     share, of Holdco ("Holdco Class B common stock") on its Registration
     Statement on Form S-4 (File No. 333-125161).

(2)  Pursuant to Rules 457(f)(1) and 457(c) under the Securities Act and solely
     for the purpose of calculating the registration fee, the proposed maximum
     aggregate offering price is the sum of (i) the product obtained by
     multiplying (x) $32.42 (the average of the high and low prices of GameStop
     Class A common stock on October 5, 2005), by (y) 41,300 shares of GameStop
     Class A common stock (estimated number of shares of GameStop Class A common
     stock to be cancelled in the GameStop merger), plus (ii) the product
     obtained by multiplying (a) $63.61 (the average of the high and low prices
     of EB common stock on October 5, 2005), by (b) 308,374 shares of EB common
     stock (estimated number of shares of EB common stock to be cancelled in the
     EB merger), minus (iii) $11,764,468 (the estimated amount of cash to be
     paid by the registrant to EB's stockholders in the EB merger). Additional
     shares of Holdco Class A common stock are being registered hereby in order
     to include a good faith estimate of shares of GameStop Class A common stock
     or EB common stock or both that may be issued after the filing of this
     Registration Statement and prior to the completion of the mergers.

(3)  Calculated by multiplying the estimated aggregate offering price of
     securities to be registered by .00011770.

(4)  A registration fee of $243,556 was previously paid in connection with the
     filing of the Registrant's Form S-4 for the registration of 54,382,484
     shares of Holdco Class A common stock and 29,901,662 shares of Holdco Class
     B common stock. An additional registration fee of $1,100 is being paid for
     an additional 284,283 shares of Holdco Class A common stock.

(5)  Each holder of GameStop Class A common stock is entitled to one vote for
     each share of GameStop Class A common stock, and each holder of GameStop
     Class B common stock is entitled to ten votes for each share of GameStop
     Class B common stock, held on all matters properly submitted to the
     GameStop stockholders.

Re:  Registration Statement on Form S-4

Ladies and Gentlemen:

We have acted as counsel to GSC Holdings Corp., a Delaware corporation (the
"Company") and wholly-owned subsidiary of GameStop, Inc., a Minnesota
corporation ("GameStop, Inc."), in connection with the Registration Statement on
Form S-4 (the "Registration Statement"), filed by the Company under the
Securities Act of 1933, as amended (the "Securities Act"), relating to the
proposed issuance by the Company of up to 54,666,767 shares of Class A common
stock, par value $0.001 per share (the "Class A Shares"), and up to 29,901,662
shares of Class B common stock, par value $0.001 per share (the "Class B Shares"
and, together with the Class A Shares, the "Shares"), pursuant to the Agreement
and Plan of Merger, dated as of April 17, 2005 (the "Merger Agreement"), by and
among GameStop Corp., a Delaware corporation ("GameStop"), GameStop, Inc., the
Company, Cowboy Subsidiary LLC, a Delaware limited liability company and
wholly-owned subsidiary of the Company ("GameStop Merger Sub"), Eagle Subsidiary
LLC, a Delaware limited liability company and wholly-owned subsidiary of the
Company ("EB Merger Sub" and, together with GameStop Merger Sub, the "Merger
Subs") and Electronics Boutique Holdings Corp., a Delaware corporation ("EB"),
whereby (i) GameStop Merger Sub shall be merged with and into GameStop (the
"GameStop Merger") and (ii) EB Merger Sub shall be merged with and into EB (the
"EB Merger" and, together with the GameStop Merger, the "Mergers"), with
GameStop and EB surviving the Mergers as wholly-owned subsidiaries of the
Company.

In connection herewith, we have examined (i) the Merger Agreement; (ii) the
Amended and Restated Certificate of Incorporation of the Company; (iii) the
Amended and Restated By-Laws of the Company; and (iv) the form of stock
certificate representing the Class A Shares and the form of stock certificate
representing the Class B Shares ((i), (ii), (iii) and (iv) collectively, the
"Transaction Documents").

We have also examined originals or copies, certified or otherwise identified to
our satisfaction, of such other corporate records, agreements and instruments of
the Company, certificates of public officials and officers of the Company, and
such other documents, records and instruments, and we have made such legal and
factual inquiries, as we have deemed necessary or appropriate as a basis for us
to render the opinions hereinafter expressed. In our examination of the
Transaction Documents and the foregoing, we have assumed the genuineness of all
signatures, the legal competence and capacity of natural persons, the
authenticity of documents submitted to us as originals and the conformity with
authentic original documents of all documents submitted to us as copies. When
relevant facts were not independently established, we have relied without
independent investigation as to matters of fact upon statements of governmental
officials and upon representations made in or pursuant to the Merger Agreement
and certificates and statements of appropriate representatives of the Company.

Based upon the foregoing and in reliance thereon, and subject to the
assumptions, comments, qualifications, limitations and exceptions set forth
herein, we are of the opinion that upon issuance of the Shares in accordance
with the Merger Agreement at the effective time of the Mergers, the Shares will
be validly issued, fully paid and non-assessable.

We do not express any opinion herein concerning any law other than the General
Corporation Law of the State of Delaware and the Federal laws of the United
States of America.

We hereby consent to the filing of this opinion as Exhibit 5.1 to the
Registration Statement and to the use of our name under the caption "Legal
Matters" in the Joint Proxy Statement-Prospectus included in the Registration
Statement. In giving the foregoing consent, we do not admit that we are in the
category of persons whose consent is required under Section 7 of the Securities
Act or the rules and regulations of the Securities and Exchange Commission
promulgated thereunder.



                                 Very truly yours,
