Smokin' Guns does not appear to support widescreen resolutions in 1.0, so I have marked it "Fail" for not being able to go to 1680x1050 to not look like crap on my LCD monitor. (There's an unofficial 1.1 which does, sort of - you have to make an autoexec.cfg and add a seta r_mode "15" command or the like to it - but I have no idea if it's compatible with 1.0 in multiplayer)
Urban Terror doesn't seem bad, besides that the graphics are spectacularly outdated. But it and Smokin' Guns are both based Q3, so I'm not surprised.
World of Tanks? I saw the thread about that and then watched a video demonstrating gameplay, but it does not look fun to me. Another MMO where you have to play to level up and earn money to buy better equipment? Not fun. And yet, they've made it worse: Once your tank gets killed in a match, you don't respawn, you can't play anymore in that match, you have to sit out the rest of the match, which can take several more minutes, until your team wins (or not), and you're awarded XP, from what that video was showing anyways. I thought about signing up anyways just to try it out and see if it was as bad as it seemed, but to get in you have to sign up for Alienware Arena, and Alienware Arena's site does not seem to actually say what Alienware Arena is.
Edit: I haven't played Allegiance in a very long time. I think I'll vote for that. Maybe we'll get a game going which doesn't involve sitting in the waiting room for 30 minutes.
INSTALLER INTEGRITY CHECK HAS FAILED. Download seems to have stopped after 7 MB instead of going to 90.7. Odd.
