I really liked Dishonored as well. Dug the setting and mood. I was also annoyed with the scroll wheel. I ended up using the numbers for the weapon swap and remapped the wheel button as my choke, because apparently I was using that a lot. Though I felt really, really bad choking that maid out. I found her cowering in the kitchen. Didn't have an option to be a gentleman and lock her in a closet or something. So I went all WWF (WWE) with the sleeper hold.
I heard Wolfenstein was a huge download. Do you know if it's because it's a long game or just large asset files? It's set in an alternate history 60's right? Will there be a Mecha Hitler?
I don't know if anyone is into civ games, but I'm very excited about Beyond Earth. It's basically Civilization in spaceeeee! Alpha Centauri is one of my favorite games. I fire it up regularly now and then. This is almost like an updated remake. It's coming out this fall (squee!)
