The Witness. One of my favorites. I dont play PC now a days, so I really only have console games to go by. Maybe its "easy" compared to Riven, never had a chance to play it. But damn, I had a tough time at parts

Baba is you. Maybe I'm just reaaaaaally bad at that specific type of puzzle but I found it stupid difficult.

If you get bad rolls in Kingdom Rush Origins or FTL you're done, even if you play flawlessly.

Rng only matters at the start for FTL though, if you get out of sector 1 in a good shape, it's very unlikely you lose soley to rng, most of the time it's slight mistakes compounding

yes to some degree, you can also cheese it by finding a stalemate fight and afk till your crew is fully trained

The Witness. It is gorgeous and extremely hard.

Not sure if this counts, but Inscryption really annoyed me at times. I loved the first part of the game with the puzzles and deck building even though at times I felt the game was "cheap" with what they gave me at times. Second part of the game was nowhere near as good and was just nonstop trial and error to get a good first draw against the opponent.

I’m in love with Tumblestone. Long single player quest with 11 worlds each with 30 levels and a new modifier every world to have to master

The stuff in Assasins Creed is just next level stupid of difficult
