just get all three then you won't have to worry if you got the right one.

I thought the xbox controller was too big when I tried it in the store but after playing through munchs odysee with it I like it
the only game I wanted / is coming soon was munchs odysee (I hate FPS) so I probably won't be using mine for a while

I really hate to say it but if you can only get one I would probably get the ps2 just because it will have more games than anyone else
