It's not unfair to say that vehicle combat games have gone out of fashion. There are very few, if any AAA franchises anymore, which is definitely a big part of why Twisted Metal's multiplayer is so refreshing. The combat in the game is just as fast-paced and competitive as a FPS or fighting game, but without the reflex-based twitchy feeling that deters players who don't have that competitive streak. This version of the game sets itself apart within its own genre as well with improved controls.
I played a round of Nuke, a multi-tiered version of capture the flag. (Those of you keeping up with the game may have seen this before.) In Nuke, one team tries to capture the other team's "leader" (read: flag), drag him to a truck with a missile on top and, after a securing period, fire a missile at the opposing team's giant statue mascot. Try to do this as many times as you can in a set period of time, then switch to defense. The mode, which takes simple capture the flag and stretches out the process, is a lot of fun.
