I absolutely adore this game, and will soon be picking this up for 12 bucks from newegg (i use gamefly, but i tend to buy games i want to keep, i.e. HOTD Overkill). The overall game is fun, its not longer than it needs to be (that said, i would've appreciated more boss battles) and, by far my favorite part of the game - the commentators.
yes, they were ridiculously juvenile - but one of the voices was the voice of bender, and anyone that loves bender from futurama will surely get a thrill from the commentators in Madworld. I would love to see a commentator feature in more games, simply because its downright silly and adds humor to something that would otherwise be a somewhat disturbing game (yes, sticking an enemy ass-first onto a road spike is funny to me, but hearing the commentators made me want to do it again and again)
um..stuff
