finished BC2 single player and starting to play BC2 multiplayer
finished Batman: Arkham Aslyum. didn't want it to end, but will probably try doing some of the challenges. the combat seemed simplistic at first (just spamming the LMB), but as more gameplay mechanics opened up and I better learned the system, there's a nice rhythm to it with good pace and flow.
got into the SC2 beta recently. not sure if I'll be playing it that much. it's the type of a game where I want to be good at but must devote time and deal with growing pains to progress, whereas in BC2, I can take a much more casual approach to playing while still having fun.
also, GTA 4 might look like ass with no mods, but I think it holds up pretty well when modded. will be interesting to see how newer hardware can push it further.
