Hand of Fate 2, feels like playing DnD solo.
Coffee Talk, for some good comfortable story and nice artstyle.
Rage 2, I heard it wasn't well received but it's a really great open world shooter. Gameplay is lots of fun.
Watchdogs 2, not that unknown but not as mainstream either, not as dark as the first one with more focus on hacking than blowing up stuff. Great story too!
Mount and Blade: Warband, probably the best game of this entire thread. It's old but aged well, mods are a must have for this one because they extend and deepen certain parts of the game play.
Monster Hunter World: Iceborne: definitely the greatest game of all time.
Got me into the MH franchise and now I'm neck deep in it. 500h+ of ingame time, none of it a waste. Iceborne DLC a must due to game mechanics and more Monsters.
Solitarica, basically solitaire with rpg elements, a lot of fun to pass time and a lot of replayability.
