Warcraft runs in dosbox I think, and is just waaay outdated nao.
itink I made Diablo 1 run under win7, and it is NOT a good game, especially the multiplayer part not working for multiplayer (though everyone uses multiplayer of it as singleplayer as only that allows difficulty change. The single player mode's random questing was btw the most horrendous part of it when it counted as innovative either way).
Hellfire never belonged to Blizzard, so that of your hope is like a dinosaur: Big And Dead
