PS2 > Gamestudio is purely DirectX and microsoft aren't about to let others use it anytime soon!

Xbox 360 > This is easier than PS2 because xbox does use DirectX. Although there are tools like XNA that can run on XBOX, it uses C#. Even if you did manage to get Gamestudio running in C#, you still have to purchase a license to make games for the xbox.

Overall as joey said, the answer is no.
