That means I'd be missing out on the groundbreakingly awesome Guardians of the Galaxy we'll be getting one day (I can dream).
So no, not worth it.
Guardians of the Galaxy was a poor choice for a Telltale style of game. I think it would be better as third person, cooperative action game. I think it would be cool if Marvel gave a huge budget to a developer like Digital Extremes (developer of Warframe) to develop it. You could get James Gunn as a character supervisor and some decent comic book writer from Marvel to supervise the story of the game. It could be pretty cool.
