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.
I recently replayed that game after 10+ years. I think I could count the number of difficult jumps that required more than two attempts on one hand. The game is like $1-2 on a sale and you can beat it in 3 or 4 hours. I thought it was fun, but I could see how it would be disappointing if your expectations were higher than minimal.
Mirror’s Edge: Catalyst was much better IMO. Actual story. Decent characters. Free roam. Side quests.
That’s funny, most people consider the story of the original to be much better than Catalyst.
It unfortunately suffers from the Ubisoft open world experience where you get so many little “go here, do this” things that I forget to care about the story.
In the OG game you’re forced to focus on the narrative because it’s a linear mission style game with each area chaining from the last point of the plot.
Plus I’m a sucker for unique art direction and Catalyst felt more like the photorealistic but boring nonsense we see constantly these days.
