nope The two developers previously worked together on The Secret of Monkey Island, its sequel LeChuck's revenge, and Day of the Tentacle many years ago. According to Kotaku, Gilbert is already designing a game for Double Fine, which has shifted its development strategy to smaller titles following the release of Brutal Legend and cancellation of a sequel.
"It's an idea that I've been batting around for many, many years," said Gilbert. "I've been talking to Tim over the last couple of months about it and it sort of percolated back up. It's very different than DeathSpank, it's a bit of a departure from that. It's going in a very interesting direction."
Ron had been coming into Double Fine to work, borrowing a desk from Tim, since Gilbert is "really horrible working at home because all I do is other things rather than work." While there, the duo began to talk about "different ideas I've had for games, kinda going back and forth like we do," which eventually led to Schafer suggesting that Ron join the team and build the game for Double Fine.
There are no details about Ron's game, though he does promise that "fans of those old adventure games [like Monkey Island] will like it," though he doesn't confirm that it is an adventure game. Double Fine will next release Costume Quest, due out this Halloween, through PSN and XBLA with THQ publishing. THQ will also publish the studio's next title.
