Mario and Sonic at the Olympic Games: about to finish it up by completing the final circuits. So much fun at parties. XDD
Final Fantasy Tactics A2 owns my soul every 2 hours before I fall asleep. Those 2 hours might be 10-12, 11-1,....12-4am :P. Seriously though, it's a great game and it's one you can put down and go back to time and time again. It'll probably take me until Christmas to finish all the quests.
My friend just got Spore two days ago, though, and he's obsessed with it. He might let me put it on my computer tomorrow; can anyone attest to it's greatness? It looks pretty fun, from what I can tell glancing over his shoulder lol.
