Trey Parker and Matt Stone explain why you should be excited for the 'South Park' video game

Trey Parker and Matt Stone are certainly no strangers to video games (See: The Stick of Truth).

But the South Park creators are particularly excited about their new game The Fractured but Whole -- think about it -- out this December.

The duo stopped by Comic-Con Friday evening for a wide-ranging chat about everything from how the show has changed over the years (Season 20 premieres in September) to the angriest reaction they've ever gotten from a celebrity (it was Sean Penn, over just the trailer to Team America).

They also shed some light on why the video game is happening now.

"We wanted it to look like you were in an episode of South Park, and the technology just wasn't there until Xbox 360 generation," Stone said, noting the junky games from the '90s. "We just hated that. So when it looked like the show we got excited."

"We knew we wanted it to be story-driven so we knew we wanted it to be RPG," Parker added. "When I [played], RPGs were my favorite...and I was big into 'Dungeons & Dragons.' And I'm totally back into it now. When you're making the game, that's really fun because [it's like] you're the DM; [instead of] anticipating what four people around the table are going to do, you're anticipating what the video game audience is going to do but you're still preparing in the same way. So that's why it's really fun, in terms of writing."

"Now that we’re making video games, it’s not like we’re these guys saying, 'What is this [video game thing] all about?'" Parker explained, noting he's a total Comic-Con guy and was making his way through the various exhibits just a few hours ago. "We’re gamers. Some of the episodes [like "Make Love, Not Warcraft"], it’s just honest because we are those dudes."

The guys have tackled television, movies, Broadway musicals and now video games. What medium might be next?

"Board games," Parker announced/joked to crowd cheers. "I love them."
