A user at the NeoGAF forums got his January edition of Game Informer (which is to feature exclusive news on the game) early and posted up a series of bullet points on Obsidian's upcoming RPG of South Parkian inspiration. The details:
-The first game Parker and Stone have directly participated in, writing the script and the dialogue.
-Parker has always preferred silent protagonists in RPG's, so the player’s character will be silent.
-The player’s character will be fully customizable.
-The player will play as the new kid in town, the main theme of the game is fitting in and being accepted.
-The story begins with your character participating in a live action role-playing game that the neighborhood kids started, which eventually evolves into a real adventure.
-Many elements of the combat system are like Paper Mario and the Mario & Luigi games.
-Timed inputs occur for defense as well for reduced damage.
-Obsidian doesn't want the player to have to sit and watch animations play out; they're incorporating dynamic camera angels at certain times, such as a Ro Sham Bo attack that stuns an enemy.
Interview with Trey Parker and Matt Stone
-Parker and Stone really enjoy rpgs and they do think that rpgs are the best fit for southpark.
-They were asked of how making a rpg story differs for an episode, they say that the learning curve was be bigger than anything they have done other then their Broadway musical.
-Parker has been a lifelong gamers, he really likes rpgs because he like the singleplayer nature of them so he doesn’t like or get MMO’s. His favorite game is Oblivion. (What. The. [censored] - ED)
