Well, I'm sure, that if there will be future MUA/XML games, they won't come in here and ask permission about, "can they use this and this mod"? Plus, I'm sure, that if Emma Frost will appear in any future MUA/XML game, than she will be in XML, either as a playable, a boss or a normal NPC, but if she would appear in MUA, than I'm sure, she would be boss or NPC. As I said a lot of times before: MARVEL: Ultimate Alliance, not X-Men: Ultimate Alliance. I mean, in a MUA game, they should use just a very little of X-Men (Like a maximum of 4, so that they can be used as a team, maybe a bit more with DLC), and more solo heroes or other non-mutant teams. Although, if they will announce, that they won't make an XML game again, but they will make MUA games, than I don't care who they use. As long as there is a chance for an XML game, than they should keep the mutants for that.
P.S: The People love Wolverine, the People want Wolverine, as long as they pay, the People WILL GET Wolverine. This how the world of money goes.
