Well, I'm playing Crisis Core: Final Fantasy VII (my second run) as well as Patapon, both for the PSP. Both games are just epic and incredibly fun! My only wish is that I had gotten the english version of CC instead of the german one but oh well >_>.
I'm also playing Mass Effect for the PC which is actually quite good. I normally don't like space-related games (find them boring for some reason) but this one's actually quite good! It's like a mix of Oblivion with one of those Tom Clancy's games.
Lastly, I'm playing MGS3 for the PS2 (using my ps3 to play, lol

). So far the game looks incredible! (But nothing beats MGS4, which is epic!!!)
