I think that if made right then these heros should get there own game.
1. Ghost Rider kinda like hitman as you are given someone that you need to go after. would work better if like splinter cell
2.Iron Man kinda like a more hi-tech version of james bond again mission based
3. Captain America like splinter cell more than one way to finish the mission, would work if set in two time zones like during ww2 and present day, with control over the shield and more hand to hand combat
