As seen below, The United States of America, The Dominion of Canada, and their territories are all Region 1 consists of. It is, interestingly, a region system that is based loosely on the DVD region code system.

Ya they may not share the same region for dvd but all games for what ever reason are released as R1. In some cases if not alot most games are just releases of the usa version. If the game skips usa the game skips Mexico if the game is edited for what ever reason in the usa its edited for mexico. A lot of games dont even have Spanish as an option in mexico they are simply 100% in English. For what ever reason if they get a Spanish lenguage on the disc some times they will release the brazil copy in mexico. Its like in Canada were some times they will release the european french copy then make a R1 French copy. Despite all dvd region or what not if you buy a game from mexico that region code be it gamecube or ps2 for example they still work here in the USA/Canada but the movies will not.
