Psychonauts and Brutal Legend? And we mean deep inside ... like, "cut him open with a lightsaber and sleep inside him tauntaun style" deep. If so, you'll want to watch "Tim Schafer's History of Videogames Adventure," a charming Gamespot documentary about the developer's life presented as an adventure game of sorts.
Did you know, for instance, that Lucasarts staffers were permitted to select Star Wars concept art to hang on their office walls? The video's full of all sorts of gems like that, and if you can get past how visibly uncomfortable Schafer is with talking about himself for this long, it's well worth watching.
