Not sure if the PC version is a good port or not, but the game itself is good. Not great, but good. Fable 1 and 2 are also quite a bit different in terms of combat than Fable 1 (worse), and there's 0 armor in Fable 2 and 3, you wear..clothes.
Anywho, the game is good, but if you're looking for a new RPG there are many better ones out there but if you're specifically interested in the Fable series, it's a good game.
