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.
To me it was immersive af, except the Johnny Silverhand levels, even though I played on a weaker rig that I have currently and the framerate wasn’t great. What I did was focus on the story and largely ditch the open world aspect, since I hadn’t been fond of this type of games for some time anyway. I played it almost a year ago and don’t remember it notoriously crashing, or at all tbh, but maybe I was just lucky.
I’m very curious about Phantom Liberty, although being a patient gamer, I’ll probably wait a bit before buying it to see if it’s any good.
