You can still try the earlier Diablo games. Diablo 1 with Belzebub mod is pretty fun (or get DevilutionX if you want a more authentic experience but with some modern QoL stuff), Diablo 2 with Project Diablo 2 mod is even more fun (probably the best Diablo variant IMO), and there’s also Blizzard’s official Diablo 2 Resurrected, if you can’t tolerate old school graphics.
