Fighting games don't play by the same rules other genres do. When you release any fighting game, devs are not prepared for the many different ways a move can be applied to. The meta evolves and the devs respond with balance changes, new characters or mechanics. I like this back and forth and seeing a game grow. But there will always be a point where players grow tired of the game. That's the moment where they need to make something new from scratch. They're starting at 0 while the old game had years to grow on top of the initial development. Considering all of that, expecting more stuff than in an ultimate edition of the old game seems kinda unrealistic.
You need to realize it's only possible to drop loads of "content" into a new fighting game if it never evolves. Tekken has that problem. It's bursting with characters, but apart from minor tweaks it's essentially the same game I played 20 years ago down to the reused animations. It's simply not that exciting. >>446470634
I can guarantee you half of those are ironic, and the other half never intended to buy the game in the first place.
