Have you tried Wesnoth, the Open Source game? Also Hearthstone is great. How about Final Fantasy Tactics? Roller Coaster Tycoon (I heard Factorio is similar)?
If you liked Diablo 2 you should research "rogue-like" games.
Wesnoth! Yes, Battle for Wesnoth is worth a look; it’s been around awhile, runs on Linux, has additional community input for the maps/modules/art/?, and doesn’t have the slot-machine quality that Blizzard has polished in its games...
Hearthstone is indeed great, and I fell too hard; while it got me of World of Warcraft and replaced nostalgia for Magic: the Gathering, the daily-quest nature of the game had me by the brainstem for years. I’ve since sworn off Blizzard games, but I understand others may be better-able to find balance.
To scratch the cardgame itch I like Pinochle, Canasta, Euchre, and others.
