Personally there are a few games which left me very dissappointed, after hyping myself up for years in certain cases.
Divinity Original Sin: turns out I prefer more streamlined, less packed games (love Pillars of Eternity) and that coop play in a CRPG stresses me out.
Wasteland 2: I actually managed to finish this one but secretly I admit I was hoping for a better Fallout which I didn’t really get. New Vegas did the cowboy theme much better.
INSIDE: while the design was cool, it was just a ton of boring, easy puzzles in comparison to LIMBO, its predecessor.
Oh man I thought I was alone with Grim Dawn! It was pretty boring.
I didn’t understand Don’t Starve for years. Its constantly rated high for a great co-op experience, so I forced myself to understand it. A few hours in, I get the appeal of why some like it.
As a crafting survival though… It doesn’t feel like you’re building anything of real value, and so you’re clearly crafting things in a particular linear order to solve the next puzzle.
