I actually did try Orcs & Humans, just out of curiosity. That was after Warcraft III was released, I believe; a little too late, and it didn't really hold my interest. I do remember that the controls were terrible. =P I did play a Orcs & Humans remake in WC3, "Fall of the Lion" by... Luthien I believe? That was pretty cool.
Edit: sorry, didn't mean to derail the thread like this <.< good luck with the project!
