I tend to like the sillier vehicles in games, like the airtugs or fagios or golf carts in GTA4, or the forklifts in Halo Reach, though the new walking mech things Halo 4 is introducing seem pretty nice. However, I've liked a lot of the things I've built in Banjo-Kazooie: Nuts & Bolts, if those count. All different kinds of planes and boats(and one time a submarine, though there really isn't enough water in the game for them) and tanks and etc. Of course there are the weirder ones my friends and I have made. After watching the Toxic Avenger 4 and deciding Kabukiman was the best super hero ever, we built giant flying heads based off him and we'd battle it out. Finally there's really cool stuff you can do they have videos of on youtube, like walking mechs or "transformers" or other cool stuff you can abuse the games' physics to make happen.
