Almost all games on the Amiga have been released on the PC also, though mostly in far worse quality. Prince of Persia is the only original game which is better on the PC, because it has less framedrops. But that I guess is because of bad coding.
There have also been remakes, like Turrican 2 and Rampart, both being better than the Amiga versions (Turrican 2 having more colours, but the same gameplay, and Rampart with more versatile gameplay).
Also, Apogee made Amiga game clones for the PC. Games like Alien Carnage (like Dan Dare 3) and Death Rally (like Super Cars). Quite good games, not original, but very fun to play.
