It has to start somewhere and instead of forcing it, he just placed him in the spot light just like everyone else for the trailer. He's only as forced as you could say Cappy is and that's the core difference, Starman is defined as cute and has a cape. Then people start looking back at his past and trophy and the whole "he could be mistaken for the hero...has the courage of one" makes him a bit more likeable especially in the wake of Superman's latest greatest movie. All factors just came together for Starman to rise into being highly likeable with very little work since he wasn't hated before and was just around. Superman ironically paved the way for Starman's big break.

Yes if I'm recalling right, he only appears in a few games as well as the golf one(a total of 11 games feature him) and none had him as someone you could recruit or buddy with.
