South Park - the Stick of Truth from Obsidian (Fallout: New Vegas among others) is a jolly, turned-base RPG with the characters from the rude, satirical cartoon that has been with us seemingly since the dawn of the Internet. It's got a trailer.[/b]
We've to a review forthcoming - a clue, it's quite a good game. But for now you can watch the trailer. Be warned though, it's South Park... so there maybe images that worry you.
