Steam Games For Two That Satisfy Our Bad Tastes

My friend and I, who are unable to hang out in person, like to play games together. We have lots of crossover in taste such as generally enjoying rougelites, rpgs, overcoming challenging content and theorycrafting. Unfortunately he doesn't like MMOs. :(

Games we both enjoyed:

Dungeon of the Endless Abiotic Factor Remnant 1 Baldur's Gate 3 Dispatch (I streamed it to him) Rematch Dota 2 (begrudgingly) Bloodbowl 2 (the best horrible time you could have) Divinity Original Sin 2 Team Fortress 2 We Were Here Series Synthetic Dark and Darker

Games one or both did not enjoy:

Fellowship Final Fantasy 14 Portal 2 Terraria Helldivers 2 Risk of Rain 2 Civilization 5 Stardew Valley Spelunky Squad Wildermyth

Lastly, for reference here are some single player games we both enjoy:

Battle Brothers Kenshi Fire Emblem Series Final Fantasy Tactics Fallout Series Xcom Rimworld Griftlands Hades Monster Train Slice & Dice Expedition Rome Demon Bluff

Any recommendations that you believe would be enjoyable for both of us would be greatly appreciated. I just want to hang out with my buddy.
