Telltale Games

Specializing in licensed, episodic adventure games, Telltale Games was formed in 2004 by disgruntled Lucas Arts workers (the cleverness department) when Sam and Max Freelance Police got cancelled. They're known for their friendly, informal approach (just look at their website and forum) and have a great connection with their fans - the moderators on the Telltale Forums are all employees.

They're very clearly in it for the art, releasing all sorts of fun machinimas and mockumentaries in between games to appeal to the fans. The interpretation of Hell seen in Sam And Max is very clearly modelled on their own office. They even published a complete Sam And Max comics treasury (the first in 12 years), Surfin' the Highway, and commissioned a new comic from Steve Purcell that was eventually nominated for an Eisner Award. So it's safe to say they've been good for the franchise.

Tropes that have to do with Telltale Games:

 * Art Shift: While most of their games are done in 3D Strong Bad's game heads towards the cel shaded direction, and Puzzle Agent heads to a 2D animated look inspired by the Grickle cartoons. The Walking Dead is done in the style of the original comic books, though in 3D.
 * Doing It for The Art: Telltale likes this a lot.
 * Hey Its That Guy: Roger Jackson and Kid Beyond pop up a lot, among others.
 * Roger Rabbit Effect: Sort of. Poker Night utilizes 3D characters for Max and the Heavy, while using the cel-shaded look for Strong Bad and Tycho.
 * What Could Have Been: Telltale games wanted to do Scott Pilgrim, but Bryan Lee O'Malley(Scott Pilgrim creator) rejected the offer. Only because he believed that Scott couldn't work out as an Adventure Game. One may wonder what would have happened if we had gotten this over a multiplayer beat-em-up game.
 * Wham Episode: They have a penchant for this, with quite possibly their best examples being the final episode of the third Sam & Max season, Back to The Future episode 3, and Tales of Monkey Island episode 4.
