Been playing a lot and really enjoying
Across the Obelisk the last few weeks.
"Across the Obelisk is a coop RPG deckbuilding roguelite. Play solo or with your friends, choose your heroes, unlock items and cards, craft your deck and face powerful enemies in deep tactical combat."
The deckbuilding part is a bit understated, first few playthroughs will be fairly unforgiving as you unlock more cards, learn what works and what doesn't. Once you have some decent cards & synergies available, and characters start to level up, you can customize decks for some more rewarding gameplay.
Difficulty sure ramps up through the 2nd & 3rd acts, makes it more rewarding when plans pay off, but sure can be punishing when it doesn't.
It's also multiplayer which is neat though I haven't tried it myself, only watched some videos of people doing it.
If you're into deckbuilding/roguelite games I'd say at least throw it on your steam wishlist to keep an eye out for a sale!
