I missed Diablo during it's first run, is it worth looking into now?
Edit: It appears there are two versions available through GoG.
"Travelers looking for the authentic Diablo experience can play the game as it was in 1996, with period-appropriate 20 FPS SVGA graphics, and the ability to matchmaker through the classic version of Blizzard’s Battle.net® online-gaming service.
For those wanting something a bit more modern, Blizzard and GOG.COM have collaborated on an updated version of the game tuned for today’s gaming PCs, which includes out-of-the-box Windows 10 compatibility, a host of bug fixes and high-resolution support."
Ha, I just came here to post this. DRM Free and FINALLY working on modern versions of Windows!
In addition, they're releasing Warcraft 1 and 2 later.

I'm going to answer this with another question. Did you play Diablo 2? If you haven't then I'd say skip Diablo and when the Diablo 2 remake comes out, get that.
1. You move painfully slow in the original Diablo. It wasn't a problem at the time because Diablo was such a unique and fresh game but compared to anything more modern the movement speed is painful for many.
2. Diablo 2 improves on it in nearly every way and the remake will come out in the next couple years.
If you want to play a slice of gaming history OR you played Diablo a ton and want to relive it then i'd say it's an easy pickup. For me, Diablo is a classically incredible game and the $10 price tag is very cheap but certain aspects of it might not make for the most smooth play through. I never owned the original but had the demo and I played the HELL of out that demo.
Diablo sets a great dark tone and because you move so slowly the dread of having monsters swarm your is felt when you are caught off-guard.
That said, I wish it had a Mac and Linux port. But you know... dreams
Apparently Diablo is now on Good old Games but also a good parent: https://twitter.com/GOGcom/status/1105591602351927297
