Recently I found a game called Grim Dawn, which is currently on sale via steam for like $3.75. So far I'm really enjoying it. If you haven't played it and are looking for something new to play, I'd check it out.
Grim Dawn is dope. it's a bit outdated at this point but they're working on a new expansion that doesn't have a release date yet. probably Q2 2026 if I had to guess.
if you haven't tried it yet, Diablo II Resurrected is great. it's nothing more than a fresh coat of paint on the original game, but it looks really fantastic. it fits the original's style extremely well, and there's a really impressive amount of detail, just like the original sprite art. as much as the ARPG genre has iterated since Diablo II, there still really isn't anything quite like it, and D2R really makes that clear. I just wish they had fixed the futzy hit detection.
Titan Quest II is currently in the works and has some positive reviews. I haven't tried it yet, but I have an eye on it for now.
No Rest For the Wicked has attracted a good bit of attention. reviews have been kind of varied but seem to be solidifying in the positive direction. it's still in early access but development seems to be proceeding at a good clip. their next update is adding co-op on Jan 22.
Darksiders Genesis is a great game that flew under the radar. it's a lot more action than RPG, but it's fun as hell and has incredible amounts of juice. it's also a fantastic two-player co-op game - one character is melee-focused, and the other is range-focused, so you normally swap between them in solo gameplay to solve puzzles or adapt during combat, but with two players, you naturally complement each other.
The Riftbreaker is a cool genre fusion kind of game - part RTS, part tower defense, part ARPG. you build bases to extract resources and craft gear for your mech, and defenses to protect yourself and your structures from periodic enemy attacks, while also exploring the map to find new resource points and enemy bases.
CrossCode is a Zelda-like with ARPG style gameplay, and some of the best dungeon design in the genre. an all-around charming and memorable game with a great story.
Gauntlet fucking owns if you have lads to play it with. it's hard as balls, has a good amount of content, some light competition aspects and tons of shit to unlock. the characters all play quite differently from each other so there's lots of replay value. definitely one of the best four-player games you can get.
there's also the whole survivors-like genre if you're into that;
Time Wasters,
Soulstone Survivors, and
Rogue: Genesia are some good entries.
personally though, I think Path of Exile 2 is the absolute peak of the genre currently, although it attracts a lot of haters.
