Easy. A superhero RPG/Strategy Game. I was a big comic book fan (Marvel) as a kid and now as an adult kid I'd love to see a company put out a superhero RPG. (And no those Capcom Superhero games don't count.

) I mean just think how fun it would be to create your own character.
A few cool looking games were going to be released. Champions (based on the old Champions RPG), Agents of Justice (X-Com meets Superheroes) but forwatever reasons they never saw the light of day.
Well hopefully one of these days a company will release a game like that for a comic-book geek like me.
