Second the mention of Left4Dead. Awesome game. I liked the fact that I could play on a team with my son—he’s very good at these things, so he was able to take up any slack in my performance, but we still got to play together. Actually, he said I was pretty good at it, at least compared to my performance in Call of Duty.
We got a Wii for Christmas, and I downloaded World of Goo from WiiWare. You have to build structures out of these sticky blobs to get from one place to another, but your structures are subject to gravity and general wobbliness (since they’re just made out of sticky blobs). The level I completed tonight required me to alternate building the structure horizontally while attaching balloons to it to keep it from falling down. Excellent puzzle game.
My all-time favorite, though, is Rayman 2 for the Nintendo 64. If they ever make that available through Virtual Console, I’m all over it.
A nice fun game I just bought is Monopoly on the XBOX 360.
Best games of the year for me was Halo 3, Gears of War Two.
