I'm really having a blast with this game. I didn't like it earlier in the Beta, but when I just recently came back to it... everything feels right. I think the powers need to be balanced (dual wield Lightning Gun with BJ Blazkowicz is ridiculous, and the telefrag power with Wrack seems completely unavoidable), but the weapons and physics (like strafe jumping) actually feel nearly perfect. I'm especially having a lot of fun with the rail gun like I always have in Quake III: Arena.
