Nah. The price dropped because it's typical Aksys crapwork with shitty quality sprites that aren't dot pixel art. It's generic doujin inspired fare which only the hardcore weaboos with no girlfriend, no life and no money.
Aksys games aren't specifically more complicated, they're just not popular because nobody really cares to play to play Doujin style fighting games in the mainstream. Hell if I wanted Doujin fighting, I could go for Melty Blood, Queen of Hearts, Arcana Hearts, or whatever. They're a dime a dozen. Just because you add the pocky infused Persona junk into it doesn't mean it's worth a whale fart.
Aksys also has a fanbase that is scared of the outside world. That's why nobody features Aksys fighting games. Evo cancelled the Blazblue tournament because Blazblue fans sat on their ass and played online and never showed up. Online is so glorious to frame friendly aksys games that they don't even have the testicular fortitude to go up to someones face and look them straight in the eye and give them a smashing good beatdown.
But ripping good price my friend. I'll wait till it hits ten dollars. When it costs less than a meal at a diner, then I'll invest into it. Gonna play some Virtua Fighter 5 now.
^There are so many generalities and -- frankly -- absurdities in this post that it's difficult to pinpoint where to begin.
Arksys games have a narrow following, I'll give you that, but that's true of all 2D fighting games today. Games such as KOFXIII and Blaz Blu, however, are hardly bad games. One could easily turn the argument around and say that one reason games like these don't sell well today is because gamers today are no longer interested in learning the complex systems and strategies that are designed into the gameplay. Personally, I think it's a combination of this, the games' very Japanese presentation (which is a turn-off to some gamers today), and the fact that these franchises have never been particularly mainstream.
I don't think one should make such sweeping judgments about who plays these games in determining why they are or are not selling. There are a lot of great games that never find their audience, and while P4A is not in that pantheon of great games, it is a solid fighter with deep mechanics.
I picked up the title recently from Best Buy and enjoy it. I am also a fan of the 2D fighter, whoever makes it, and it's nice that developers will still build games like these. Looking forward to Darkstalkers.
BTW, don't lump Arcana Hearts with the likes of P4A -- that game was horrible.
