All of those sound pretty good. I've been playing a lot of Team Fortress 2 myself lately. It would be cool to have some regulars to play with. Any of the other games I like to play have a bit of a learning curve, require a bit of a time commitment to finish (well, depending on how it was set up, that might not be an issue, they are kind of like a mix of sandbox and strategy games so it could be feasible) and are a little pricey (not a big deal, over the past year they've been on Steam sales like 4 or 5 times, dropping in price by quite a bit actually). On a semi-related note, if anyone has Crusader Kings II or Europa Universalis IV, it would be nice to have someone to play with lol.
The position is open Kalthrix... want to take it over?
