Valheim is broad but not deep enough and its success is mostly due to when it appeared. If it weren't in the early access cycle and the devs had made the game they wanted to make instead having the community poke and prod them it probably wouldn't be very fun.
Satisfactory is absolutely hampered by the unreal engine's limitations.
TLoZ: A Link to the Past, the enemy respawns get annoying when backtracking.
Chrono Trigger: Rewired my brain to make me like DBZ character design
TLoZ: OoT & MM: gave me nightmares which I was not expecting going into them from the previous games in the series
Super Metroid: led to me constantly waiting for MP4 but it's totally coming this year for sure. The sheer missile-sponginess of the bosses is kinda tedious I guess?
Any Tribes game: it will never be the same and I am sad.
Dwarf Fortress, Kenshi: I cannot play these anymore because I forget to eat in real life and I will die.
Red Alert series: Yuri was kind of a misstep I feel and limited the series' development.
Sim-Anything: Maxis selling to EA for a cash grab ruined one the coolest studios ever to exist.
