How is Elex? Trying to find an openworld RPG and Steam recommended me it.
It's very good as an RPG. The quests are very interesting, most intertwined with others (so it's not even rare to mess up or complete something before you knew the full picture), and they do have huge consequences for the choices you make, including entire factions turning on you forever.
Also it's a PB game, so loot is scarce, but extremely powerful. When you're fully decked out you're almost invincible, and that's cool.
However balance is pretty rough; it's hard early on, a lot of items require too much stats to be worth it, the UI is very lacking, and the combat is an awful mess.
Melee is... pretty damn terrible. Ranged combat is just serviceable, magic is a bit fiddly but works... potentially
too well.
For a game with a similar feel to Piranha Bytes games, I'll always recommend Outward. It's pretty much Gothic, but better, outside of the poopy story segments. And it has online coop.
