7. Psychonauts
Psychonauts is a great game and it's still fun to play today. It has a great story and it was in general a really great experience from the creator of Grim Fandango, and while the game didn't receive the great financial reception it deserved, it has a great fanbase that would love to see more from Raz and the Psychonauts. While a sequel has been in the works since, well, forever, a TV show might help to mark their return. If a TV show based around the game proves to be a success, investors might find attractive the idea of funding a sequel. Besides, wouldn't it be cool to see a TV show based around the game's premise? This is one of the few games that has a story like that one without being ridiculous or childish, so I think they should exploit it more, to the benefit of the fans.
