Alternatives for Diablo 4?

path of exile

If you are looking for a bunch of Diablo clones I'll recommend the Torchlight series, Titan Quest, Depths of Peril, Victor Vran, and Path of Exile. I've played these to one extent or another and liked them.

Someone here probably has an exhaustive list of Diablo clones but I'm too lazy to find one.

Path of Exile. Its free... unless you plan a ton then you will want to put $20-60 in for stash tabs and cosmetics(then you will never need to buy anything again... unless you want more unnecessary space as a hoarder... or more cosmetics)... you cannot buy power.

and of course... Diablo 3, Diablo 2 resurrected as better Diablo alternatives.

Titan quest and torchlight are also viable options.

This site tends to recommend similar games better than steam's recommendations

Last Epoch is really good
Path of Exile is great if you like to work hundreds of hours on your build
Titan Quest 2 is coming out soon

Path of exile

Well tried PoE but not my like. Waiting for Titan Quest 2.

Wolcen, Warhammer: Chaosbane, Torchlight II, Lost ark

Torchlight 2 with mods is amazing. Be sure to download a workshop modt that adds a lot of new classes.

Path of Exile hands down. Don't let the complex passive tree intimidate you.
