It's also hilariously NSFW. In this near 15-minute long video, you'll see how South Park: The Stick of Truth plays and get a sense of its presentation. Spoiler: it looks just like the TV show.
Although it's suffered months of delays as Obsidan and the South Park creators have been, in the words of Trey Parker and Matt Stone, "Getting the game up to the crappy standards of the show." Seems like all that time in development is paying dividends, as this small slice really shows off its humour, and is already loaded with in-jokes and references for eagle-eyed fans (see if you can spot the Chinpokomon).
It's been a big few weeks for The Stick of Truth, with this video that goes behind the scenes of the game, and also a spoiler-laden achievement list.
For more info and impressions check out Jon Blyth's preview from late last week. South Park: The Stick of Truth will be released for Xbox 360 on March 4 in the US, March 6 in Australia, and March 7 in Europe.
