In the classic post-apocalyptic vein comes Auto Assault, a driving-based MMORPG from NetDevil and NCsoft.
With the ability to fly (drive?) solo or join up to various factions to fight the bandits/mutants/greater evils of the wastelands, this could be your sort of thing if you're tired of wizards and their beards. With the Havok physics engine behind it, it could be a good laugh to speed around in.
If you're interested, give this video a look - it's an interview with Scott Brown, and includes more footage from the game.
