This is something I've always said. BUT you need a community that's based in it. There are two things that were going for Marvel 3 and Melee:
- A culture of hero worship and hype (thus the Smash Bros, Yipes and the Chris G/Flocker/KBR etc)
- They thought they were never going to get another one. Melee players realized they'd never have a game built that way again. When Capcom lost the Marvel license, most people assumed that was the end of MvC as well.
If you have those factors, you can sustain even through the most broken titles with community spirit.
In fact, WE had that spirit in MK9. It was a terribly broken game, but we sustained it through pure love. But we do not have that spirit now, and we know that. The current generation is much more entitled that we were in 2011 -- and having a reasonably balanced game is something that many people consider to be the threshold for staying interested competitively at all.
At this point we know that this community won't sustain hype for a game that's terribly broken. So it makes sense that, after having been yelled at for multiple years straight, the devs decide to play it safe in favor of competitive integrity first.
