go discuss stuff and make concepts of a new game
Try "Sam & Max Save The World", which is more of a classic point-and-click adventure game than a choose-your-own-adventure-choice-type game. This was one of Telltale's first games, and it has been recently remastered by Skunkape Games, which acquired the license from Telltale's financial troubles. Skunkape is working on the other Sam & Max seasons as well.
Similar style games that Telltale still offers are Tales of Monkey Island, and Wallace & Gromit's Grand Adventures. There's also Puzzle Agent and Puzzle Agent 2 if you like solving individual puzzles. And there's a poker game or three out there somewhere, too.

please make a concept that telltale has never done before (only non-choices games)
