I just want Wesker in, in one form or another. Even if he's just in mercs again that would be fine with me.
And Jill.
Jill is in Revelations. She was also in RE5, Mercs 3D, RE3, and RE1/REmake. Also, Umbrella Chronicles.
If you look at Chris, it's similar. He's in Revelations. He was also in RE5, Mercs 3D, Code Veronica, RE1/REmake and Umbrella Chronicles.
These characters already have a lot of non-bullshit representation in the series. Leon, for example, has plenty of representation, but look at this:
Leon is in RE4, RE2, RE: Degeneration (a movie that no one cares about), Operation Raccoon City (where he plays the dumb role of the guy you want to kill), and Darkside Chronicles. Oh, and RE: Gaiden which nobody cares about or wants to remember.
In terms of the main Resident Evil cast, I hope for there being no trace of Jill in RE6 and I was originally hoping for no trace of Chris either. We've had enough of these characters already in the RE games that actually matter. I definitely want more underrepresented characters like Barry and Rebecca in RE6 as well but I doubt I will get them so I won't keep my hopes up. I like that Leon was included because he deserves to be in another game that people actually care about, even though he's already been represented a lot across the franchise and is in the arguably best game in the series (RE4).
Claire is similar. I'd take her over more Chris or Jill as well. Again, she's made multiple appearances but only two of them are really worth a damn.
So in short, I don't see how anyone could want MORE Jill in RE6, and I don't see how anyone could not be disappointed in MORE Chris considering that these characters are already overly represented in the series and are actually the main characters of a new full-fledged RE game that's releasing in a matter of days.
Leon, Claire, Ada, Barry, Rebecca. This is what people should want to see!
