We love Blizzard's popular game, Diablo. We love it so much, in fact, that we're willing to spend our precious time developing a free and open source solution for those wanting to play it on a modern computer.
Short answer, yes. We don't distribute any copyrighted game assets, which means you'll need to have a copy of Diablo to be able to play.
Probably the only feature half of you even care about :p Anyway, perhaps an overstatement, as what you see is just the player being synced, but I’ve started on implementing mp, so you should be hearing more about it “Soon”
