$12 but still much more expensive than most games. I think they forgot they released this game on iOS and not PSN/XBLA where it still would be considered pricey for such an old game.
With that said, my friend has it and I played it for a bit, it runs perfectly, looks nice and sharp, and the controls are fairly tolerable for a fighting game on a touch screen.
Is definitely IS expensive for such an old game. It's identical to the Dc version... even the audio samples have that crunchy quality to them. It's more playable than I would have thought,especially if you lay the iPad down at about a 40 degree angle and use the tips of your fingers,rather than holding it and using your thumbs. It's very responsive, all the moves etc are there, it runs super smoothly and loads up in a split second.
You'd expect all that in a 13 year old game; but playing it on a slab of glass still seems surreal. I'm hooked.
