Fable 2, it was fun and all, but, well, nah.
Condemned 2, I couldn't get very far because half an hour in and I just decided, that, well, no, I don't want to get into the goo shit, why are weapons deteriorating now, what. The. Fuck.
Sonic Heroes, I know, I know, it's just that I really liked Sonic Adventure 2 and thought the next game would be awsome. It wasn't.
Advance Wars Duel Strike, I loved Black Hole Rising, you got to be each different nation (except for black hole) and they all had a unique look. All you get in Dual Strike was orange and while the core gameplay was unchanged having to deal with two battles in each mission pissed me off because it favoured an umbrella strategy and didn't give way to the advanced thought that one faction gives you.
DC: Soulstorm, the changes made to the campaign pissed me off to no end. My Imp guard can't even break on to the second planet.
The Witcher, do not really want a MMORPG.
