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.
The “Can it run Crysis” thing was purely about the fact that it was one of (if not the most) resource-intensive games out at the time. I remember it being a big jump in terms of both visual quality and the requirements to run it well.
Yeah, I remember in the early 00’s people saying the same thing about rendering Balmorra with a double-digit framerate.
