So, do you really expect Xrd to die off?
Expect? No, because as you just said the pool of people who don't care whether a game is good and are willing to justify playing crap cuz it's new is bigger than the pool of people that will play what is good despite the age.
Hope? Yes, becuase Xrd is IMVHO a really terrible Guilty Gear.
I mean, after SF4, how many stuck with 3rd Strike?
Enough that I can still play it at Super with people who don't suck. That's fine with me. It doesn't bother me if the majority of people I don't care about move on to New And Shiny, as long as the people I do care about continue to play Games I Enjoy.
Small rant:
The FGC has largely left behind all the games I see as having any semblance of fun, good pacing, enough neutral, or balance. This seems largely due to fighting game developers having lost all the people who have any understanding of fighting games and their real nuances, so all the new games are just kinda starting the learning process of how to make decent gameplay over again. AC+R was a small step sideways from AC, but at least it kept the sense of what AC had.
The thing that makes me sad is that there are people who have been playing fighting games since 2009 that think the current crop of junk is what fighting games
should be, or the final evolution of what they can become (and that they won't play anything older because it's old, or hard, or whatnot). I see people forcefully argue that all anime games have loops and unblockables and most games have infinites - why do we, as a community, ACCEPT THIS?
It takes a long time to get comfortable enough with (note I did not say "good enough at") Third Strike or MvC2 or GGAC [or CvS2 or VSav or whatever] to appreciate why they work the way they do, and most people aren't willing to do that because it involves losing. Besides KOF, I haven't entered a game at Evo since 2010 (and I sincerely doubt SG will be in there this year so the streak will probably continue). SF4, MvC3, BB after CT, and now Xrd are just so un-fun for me because for a long time I played games that didn't have the problems they have! But I'm one of the only people I know that has those kind of standards.
I skipped mentioning SG anywhere in there because I don't want to egoize.
