I've been using mods and hacks to get this game working for 20 years, my friends and I take a night and beat through it again at least once a year. So, sooo happy to see it finally on GOG! This is my personal favorite of the entire Diablo series. Diablo 1 is a child of the original roguelike genre, and I love the "rogue" feel here that I don't get from later games in the Action RPG genre it spawned (games more steeped in story and evolving modern game mechanics, including later Diablo games). I also love the gothic plot, just enough plot to set the mood, not so much that the plot becomes the point, because it's really about exploring the dungeon. It can be unforgiving. When you die you have to get back to your body to recover your gear, sometimes that's a real nightmare (use town portals to lure monsters away from the body, and don't quit the game until you've recovered it). Some monsters don't open doors, use that to your advantage. Remember to repair your equipment, if it breaks it's gone forever and it it really sucks to lose that prized item because you put off repairs. Especially if you're the Rogue character because every shot damages the bow a little bit. Randomness matters too. You only have the spells you find and that can change the entire game. Multiplayer takes about 10 hours, you can beat it in one weekend (or one night like we do). That makes it ideal for a long night of gaming with friends. It's balanced best for 2-3 players, with 4 you'll slowly become under-powered. Even with three players we sometimes restart the server and replay from the catacombs if the caves or hell are too difficult. Even with those replays 10 hours is about right though. Finally, yes the interface is dated. You have to navigate text-based menus with the keyboard when you talk to NPCs and things like that, but once you get used to it it's not bad at all. If you want an old school roguelike dungeon crawl I can't recommend it highly enough.
