None of the MVP games are backwards compatible.

That's, well, that's just bullsh*t. I didn't know that until tonight when I sat down to play MVP 2005.

now why would you want to do that when you have the stellar MLB2k6 offering native on the 360? /sarcasm

i have some high hope for the MLB2k7 game. the trailers and clips look promising.
otherwise i'll have to go back to playing the Sony MLB game on the ps2.
