I asked this a while ago back on the front page but didn't get a response; what, exactly, makes this a "niche" title? It's a 4-player online fighting game.
Did you just answer your own question? Even 1 on 1 fighting games are in decline, hell even SF x Tekken bombed (the fact that it's the worst fighting game to be made in the last decade probably helped it fail, granted...).
It's not like we're talking about some strange 3DS crossover Stategy RPG or something....
this game looks like it's just a really fun time.
Unfortunately, fun has little to nothing to do with popularity.
People like 4-player fighters (they brought Brawl by the millions) and this one has online play.....I dunno. Not really sure what makes this a niche title other than "it hasn't been marketed."
As Aki said, people don't like 4 player fighters, they like Mario and Friends Party Game
TM.
I think that you are severly over-estimating the open-mindedness of today's market. Big franchises are getting bigger (or at least, shrinking less fast) and everything else is just about in the toilet. This sort of concept would have worked infinitely better as an XBLA game I think.
What really makes me feel sad is that they seem to be putting so much emphasis on multiplayer, and you just know that the servers are going to be a graveyard within a month.
On a purely personal perspective, I don't know how to feel about this game. First of all the graphics look bad. This might be because it's catered to big online arenas though. Secondly, I find the aesthetics nowhere near as nice or interesting as their previous games. The gameplay has moments of looking really good and really strange. I'll need to play a demo to see what I think of it. As I said before though, the biggest issue I can see is the focus on online play, and it'll probably be dead within the month. I'll probably end up getting it, just in the hope that at least the single player will be fun, but i really don't know...
I see no hype, I see no interest from even most of Platinum's fan who know this is coming, I see nothing
The game does have somewhat of a following over at shoryuken.com, so that's something I guess.
