"Diablo-esque" game that runs on linux (preferably free) [closed]

I think the closest games to Diablo are Torchlight 1 (Humble Bundle Store) and its successor Torchlight 2 (Humble Bundle Store or on GoG). In fact, part of the developers of these games, were inside the Diablo development team.

If you have a system with enough muscle (mine is a Core2Quad 2.7 GHz, 4 GB RAM when I played the game regularly ), I've found that the free¹ game Path of Exile runs reasonably well (instructions are available for installing with Wine or PlayOnLinux).

Compared to Diablo, it's like moving up from Tic-Tac-Toe to four-player Pente -- it's a MMO isometric, with seven character classes, ten acts, huge numbers of item drops, maps, and it's "live" -- that is, new material is still being added on a regular basis, as one might expect for an MMO.

¹ “free” as in “free beer”. It’s not open source software. The game development is (supposedly well) funded through purchasable player and weapon skins, a sales strategy dubbed “pay-to-shine”.

Just to help you find stuff yourself, I'd categorise Diablo as an isometric action RPG.

There are probably a few options here but in the non-free camp:

• Freeablo is an engine reimplementation of Diablo 1
• Wine can be used to play the Windows clients. For example, Diablo 3 does work quite well (with caveats).
• Victor Vran is very similar in gameplay and tone to Diablo. Again, non-free. (I honestly hadn't seen the comment on the head post! Thought this independently when I saw the recommendation for Torchlight)

FLARE is pretty much word-for-word what you asked for: Diablo-like, runs on Linux, free. It's been a few versions since I played it, so I don't know how much depth there is to it nowadays, but it was good for a couple of hours' hacking and slashing even back when I first discovered it.

It may be worth noting that FLARE is both an engine (the name stands for Free/Libre Action Roleplaying Engine) and the included game built on it; it seems like maybe the preferred capitalisation for the game is Flare?

Some (arguably most) of the Soldak Entertainment games are similar to Diablo, such as Din's Curse or Zombasite.

Both are isometric action RPGs where gameplay consists primarily of an isometric action-RPG dungeon crawl where you acquire random loot and build up your character. Soldak games do tend to add some additional quirks, though (such as procedurally generated quests).

I've gone with Steam links, due to personal preference. The games are also available from the developer's website directly.

Other games from the studio may also be worth looking into, such as Drox Operative (a Soldak-style diablo-like "in space!", as it were).
