Alice, you must play FF7. Repeat with me, "I must play FF7". It's the best FF game IMO. Good story, good character development, good music, and the graphics aren't bad either, plus the gameplay.
However, like Ultima said, I have had trouble finding FF7 for PC too. Only the playstation game. My own copy is so scratched, I want to buy a new copy, but I guess I'll have it polished.
