Grapevine, Texas 76051
Ladies and Gentlemen:

We have acted as counsel to GameStop Corp. (the "Company") in connection with
the Registration Statement on Form S-3 (the "Registration Statement") filed with
the Securities and Exchange Commission under the Securities Act of 1933, as
amended (the "Act"), and the rules and regulations under the Act (the "Rules"),
with respect to 9,115,950 shares of the Company's Class A common stock, par
value $0.001 per share ("Class A Common Stock"), issued to EB Nevada Inc., Agnes
C. Kim, David D. Kim Trust of December 31, 1987, John T. Kim Trust of December
31, 1987 and Susan Y. Kim Trust of December 31, 1987 (collectively, the "Selling
Stockholders") and to be sold by the Selling Stockholders in the offering
contemplated by the Registration Statement (the "Offering").

This opinion is being furnished in accordance with the requirements of Item
601(b)(5) of Regulation S-K under the Act.

In connection herewith, we have examined the Registration Statement, the
Company's Amended and Restated Certificate of Incorporation and Amended and
Restated Bylaws. 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 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 certificates and
statements of appropriate representatives of the Company.

In connection herewith, we have assumed that all of the documents referred to in
this opinion have been duly authorized by, have been duly executed and delivered
by, and constitute the valid, binding and enforceable obligations of, all of the
parties to such

documents, all of the signatories to such documents have been duly authorized
and all such parties are duly organized and validly existing and have the power
and authority (corporate or other) to execute, deliver and perform such
documents.

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 the Class A Common Stock has been duly
authorized and, when issued in accordance with the Company's Amended and
Restated Certificate of Incorporation, will be validly issued, fully paid, and
nonassessable.

Our opinion herein reflects only the application of the Federal laws of the
United States and the General Corporation Law of the State of Delaware. The
opinion set forth herein is made as of the date hereof and is subject to, and
may be limited by, future changes in the factual matters set forth herein, and
we undertake no duty to advise you of the same. The opinion expressed herein is
based upon the law in effect (and published or otherwise generally available) on
the date hereof, and we assume no obligation to revise or supplement this
opinion should such law be changed by legislative action, judicial decision or
otherwise. In rendering our opinion, we have not considered, and hereby disclaim
any opinion as to, the application or impact of any laws, cases, decisions,
rules or regulations of any other jurisdiction, court or administrative agency.

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 prospectus filed as a part thereof. We also consent to your
filing copies of this opinion as an exhibit to the Registration Statement with
agencies of such states as you deem necessary in the course of complying with
the laws of such states regarding the offering and sale of the Class A Common
Stock. In giving such consent, we do not thereby concede that we are within the
category of persons whose consent is required under Section 7 of the Act or the
Rules and Regulations of the Commission thereunder.

Very truly yours,
