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.
Whenever I played Hollow Knight I maybe got an hour or two in and just stopped because I didn’t know what to do. I wasn’t really given directions and I didn’t know where to go. I swear I spent an hour just looking for where to go and I fought only a couple enemies in that time.
I had just finished playing Stardew and Enter the Gungeon, and I was really tired of tabbing out to look something up in the wiki or a forum, so I just wasn’t willing to commit to another game without instructions.
