Grand Theft Auto 5

[Kalyx triaD]

Grand Theft Auto V comes on two 8GB discs on Xbox 360; the first is a mandatory "install" disc, while the second is the "play" disc. While you'll have to install the former (as you might have guessed), the studio has warned against trying to do the same for the latter as it'll negatively impact how the game runs.

Might be similar to what occurred with Halo 3 when installs became possible on the Xbox 360. Either Rockstar hard coded some stuff for the game or the streaming feature was never designed to run from one source.
