GameInformer's drip-feed of extra South Park content continues seemingly all month long. In this instance it's an interview with lead designer Matt MacLean (super nice guy btw) who details some of the finer gameplay points Matt and Trey have had a hand in tweaking.
Most notable is the games five classes. When you start your character off on his adventure through the quiet, redneck, white bread mountain town, you'll choose between fighter, thief, mage, cleric and Jew... Jew... yes, Jew. Turn based combat comes with an action-button style Paper Mario twist to it.
That means hit the button at the right time and your attack will do more damage. Hit it at the right time and your character will defend against incoming damage. Have you not played Paper Mario before?
Seems pretty clear Parker and Stone know what they're looking for in a game. Check out the link for the full interview.
