I wish I could make the time for that as I really still do love Diablo.
Not sure if any of you care enough or not, but ever heard of Bezelbub HD?

Install D1, throw that MOD to it, and the game will be almost like new again. 1080p possible, all looks the same but can be sharper, runs in 30 or 60fps. All the problems modern Win7 and later 32/64bit can cause with the old game are resolved and adds a few tweaks like zoom capability for one, and always run as another (game walks slow compared to D2.) It does add a few things like weapon swapping and some crafting but the core game remains.
