... but even they suffer from cheap 3-frame dialogue animations and choppier animations in general. I'm pretty sure they don't run at 24 fps most of the time, unlike Akira.
Perhaps that's it then. . .Personally I don't consider frame rate having much correlation at all to animation quality when it comes to Anime as that is part of the structure of the medium. In my opinion, having issues with an Anime's frame rate is like criticizing a Film Noir for not being filmed in colour or the Scott Pilgrim game for looking like an old NES cart.
For a cheaper price (how cheap ?), I think it may be a good buy. However, do you have other games in mind ?
Darkstalkers comes to mind. I picked up this game for something around $30 and at that price, got a lot of value out of it. It's easier to overlook the odd issue in a game when you are not forking over $70.
Enslaved looks like it might be a fun diversion while waiting for this PS3 game drought to end (everything I am interested in seems to have been pushed to 2011).
