That's a really bizarre argument.
You can't compare our scene that way. MK games die and they stay dead. However, I will point to the rocking MK9 revival tournament at ComboBreaker from JUST LAST YEAR to show how hype and loved the game is. That'll never happen for the other installments, and MK11 will be lucky to see Evo a second year much less the FOUR that mk9 had. MK9 wins on legacy and importance alone. But it always wins in sense of speed, roster, music, stages, rhythm, etc.
What's actually bizarre is that you are saying I can't make an apples to apples comparison. Why are MK games treated any differently than other fighting games in terms of support and longevity? Perhaps you may not have been around during the days where fighting games from a company like Capcom had tons of supporters for each version of their games.
Players would hop from Alpha 2, Super Turbo, Alpha 3 and 3rd Strike. Each game had a solid community behind it. Why did they do this? Because those games had legs. Top notch game play and lots of fun. MK9 is fun, but due to gameplay related issues, it is no longer played consistently. If it was that good, it would be. That's all I'm trying to say. I was not out to make anyone feel like they can't have an opinion on the this.
But when we say "Best NRS game of the decade," I don't believe this one still holds up. Again, it's just my opinion. Perhaps I'm wrong but I just played MK9 online recently and it reaffirmed my position on it. Fun game, but not my NRS game of the decade. It does get credit where credit is due since it was solid enough to be accepted by the fans and the FGC alike.
