Well I think there are steam groups dedicated to just this so maybe you can join into one.
I dont pay attention to achivements so idk, but almost every newer game has them now so you cant go wrong.
Im playing Deus Ex Mankind Divided. This is a really good game for a completionist and it has achivements.
Reviews said this game is short, and it can be if you ignore everything around and just stealth past all the enemies.
But if you actully stop and look around, explore, well I play pretty slowly with a beer in one hand and its taken my like 30 hours to get about halfway through the missions.
But start with the previous game Human Revolution because all the characters are introduced there and its probably even a better game.
Also
Saints Row 4
Alien isolation
Talos principal
Soma
STALKER games (all 3)
Those are some good pc games, some of them arent even on console I dont think.
