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.
Diablo 4
Really loved the first cinematic and enjoyed the Beta. But I’m already bored after reaching lv 30. Haven’t played it in weeks. I don’t know, the MMO aspect kinda ruined the expirience for me and the combat isn’t fun enought to keep me engaged.
