Kids? I mean last I checked kids like Charizard and Mewtwo and Blaziken and Pikachu and Lucario and whatnot. To me it seems like a mix between unconventional choices and painfully conventional ones. Kids are also fine having fun with a game instead of trying to turn pro with it. And Pokemon may have a large demographic of kids, but it has a large demographic of adults, and mixed with the fact that it's a more traditional fighter (and it's even being pushed at EVO), which usually skews more towards the dedicated, older gamer, it seems like the demographic Nintendo is going for is not the casual kid with this one.
And I guess the first part is a matter of opinion. I was looking for a competent, viable spin-off traditional fighting game from Namco, and I got what I was expecting. I didn't expect it to blow me away, and it didn't, but I'm certainly not disappointed with it. Especially since the combat system is unique, and some of the character choices are pretty antithetical to normal fighting game affair, which is some nice diversity.
I did think we'd get a couple more characters, but like I said, 16 characters is pretty normal for the first iteration of a fighting series.
Again that's subjective. I got my money's worth on Soulcalibur II and MvC 2 and 3, and SFIV many times over and I have no illusions about being anywhere near pro level. Plus, even with niche genres like the traditional fighter, it's still the minority that participates in the FGC. SFIV sold like 4 or 5 million or something (idk), you think all of those people are active in tourneys and whatnot?
And the game is hardly masquerading as a typical Pokemon experience, I mean it doesn't even have the word Pokemon in the title.
People are also clamouring for a Pokemon MMO, but that's hardly an immediately accessible experience for those unfamiliar with the genre, does that mean it shouldn't be attempted? Mario ventured into RPG territory a while back, itself a genre more niche and complex than a platformer, but that seemed to go over fine as well.
