Maybe because I'm extremely tired, but I think you guys misunderstood my Sunfire post. I wasn't comparing the popularity between him and Dr. Strange with the Marvel nuts, I was alluding to the fact they are both obscure as hell for a general audience. Of course, Strange is far more popular with Marvel nuts and way more important to the Marvel universe, compared to Sunfire, who is a very minor character.
I've seen numerous people in game this past month saying they've never heard of Strange or even Rocket until the game/GotG trailer. I was saying that 90% was a general audience that doesn't know much about those Marvel characters. So, Gaz/Marvel are willing to put in obscure heroes/anti heroes, but again, yea Strange is important. Gonna end up having to explain Strange to friends if that movie ever gets made, since they only know of a few mutants and Avengers. Hell they didn't even know who Colossus was or the cameo or whatever you call it at the end of the newest X-Men movie.
