there is nothing you cant do without the disc...it literally just allows access to game saves. Trouble is, you can already do this from many other sites. Companies like this are really having to scrape the barrel what with the rise of trophies and achievements, the games ship with few to no cheats hidden within the game code, and many game saves are now locked to the original users console or online account. They offer nothing anymore. its not the same sort of thing you found on ps2/xbox. those days are gone now. all it does is charge money for things you can do onlne for free anyway. avoid!
