The new kingdom hearts and Disidia is a must, plus I have not played those yet. It's a shame MHF3 is there instead of MHFU. MHFU is a far bigger game.
I'm guessing the games will have adhoc party functionality built in since it's a separate app on the XMB for standard PSP games.
Awesome! I'd love to play the FF and KH versions from the PS3. Yes, I do own those on the PSP though.
I thought FF:CC got a bit boring after a while, I have no desire to even go back and play the PSP version let alone fork out again if it comes to PS3. Mega Man Powered Up and Maverick Hunter X (which are both pretty rare and not cheap over here) on the other hand I would jump at.
