Game Informer continues their exclusive reveals on the recently announced official South Park game with a lengthy video interview with developer Obsidian Entertainment's CEO Feargus Urquhart as well as a print-only article in their January issue, offering a bunch of new details.

Fortunately, for those of us that don't get our gaming news stamped on dead trees, the intrepid folk on the neogaf forums have plucked all the points out in point form, so here's a condensed summary of some of the more noteworthy ones:

Built on the same engine as Dungeon Seige 3, South Park will take the form of a 2D RPG that very closely resembles the look of the TV show, with a dynamic lip-syncing system that allows them to rapidly add and alter dialogue.

South Park creators Trey Parker and Matt Stone are heavily involved in the project, having written the script and dialogue as well as seemingly having a lot of creative influence over the direction of the game itself. Parker mentions Oblivion and Zelda among his favourite games and isn't a fan of MMOs, while Stone cites more action-oriented open-world games like Batman: Arkham City and Red Dead Redemption as his preference as well as sports titles NHL and FIFA -- joking how their ideal would be a cross between Oblivion and FIFA where "you gotta go kill a bunch of monsters and shit but you can only use your feet".

Other promising bits of note are the mention that Parker hates unskipable cut-scenes and that when Obsidian pitched Matt and Trey with a quest that had the player go into a cave and fight a giant bat with a South Park character riding on its back, they rejected it as being too generic and not South park enough, using an example of getting Kung Pao Chicken from City Wok as more on track.

The player character will be a voiceless newcomer to South Park that can be customised to their preference and the story will begin with as participation in a live action role playing game that evolves into a real adventure with five character classes: wizard, paladin, adventurer, rogue and a fifth undisclosed and reportedly unconventional class imagined by Eric Cartman.

The game will feature an exhaustive amount of items and imagery from the show such and is the first time they've actually had to consider how the layout of the town of South Park all fits together. The actual playstyle is described more like a JRPG in combat, with Paper Mario and the Mario & Luigi games cited as examples.

South Park The Game is due "sometime in 2012" on PC, Xbox 360 and PlayStation 3.
