A bit different but I've been spending a lot of time playing Path of Exile recently. I would recommend ignoring any meta or the economy and treat the game like a roguelike instead. The shear amount of items/abilities/passives/mechanics make for insane build diversity. Learning stuff and planning builds is as satisfying as the gameplay. I spend about as much time ingame as Path of Building (a build planner)[1].

Here's a short showcase showing what some of the mechanics are like: https://youtu.be/S8vRgG9LrIg
