I do have to say that if you don't like fighters (I sure don't), and if you aren't much of a PCE collector, then the almost sole-reason to get the card is Sapphire. The arcade card is cheap, but if you're looking to be choosy with how you spend your money, you should really do everything you feel good about doing to assess this one game before you buy anything.
On the other hand, if you're talking about also getting original, non-bootleg copies of Sapphire and any other AC games, then you need to take 10 times the care. Sapphire is so expensive, I really can't recommend it to anyone other than collectors or hardcore shmup fans. I think it's a great game, too.
