Right now I'm playing:
Dementium: The Ward - So far a very fun DS FPS/Survival Horror game. Something I never thought would exist on the DS (let alone be successfully pulled off).
Disgaea: Hour of Darkness - I've never played a Tactical RPG before so I thought I'd try one. I like the character designs and it got good reviews and so far it's pretty cool.
Indiana Jones and the Emperor's Tomb - This is a relatively old PS2 game that I picked up just because I've been excited about Indy lately. I wasn't expecting it to be very good but I'm actually quite surprised by the fun gameplay, solid story and quality voice work. The graphics, however, look like something from the PS1.
I've recently finished:
Resistance: Fall of Man - Awesome! I can't wait for the sequel.
MGS2 & 3(again) - As I said above, these games are great. There's nothing else quite like them.
You playing anything good?
