SE Avengers game of course, MUA is certainly not an Avengers game.
Also my point is that when a franchise started to grow and gets adapted, the characters who came all this way to build up this franchise should be given the share of benefit they deserve.
I don't mind more characters from other corners of MU to be in it, but seriously some people just act like a squatter who wants to take others places earned through history for granted.
Also that's kinda the point, before there is sessions, approvals and they get their Avengers ID cards like a formal ritual.
Every new recruit means something for the Avengers team and the new member.
Now they just gather a group of heroes and slam the Avengers name on it.
Well, it's kinda my gripe with team-only Avengers got treated like fourth class citizens in Avengers books these days below Big Three, solo character that aren't in Avengers books much and whatever new characters they are pushing.
