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.
Quite literally the best description of it. I enjoyed it. I played it through 1.5 times. I’ll probably never touch it again.
When the only thing I remember fondly of it is “It’s not the best choice… it’s spacer’s choice!”… eh. I think they tried to be Fallout in Space but failed because of imperfect mechanics and (of all things) not taking itself seriously enough. I’m waiting for slapstick when I see a brand advertised as “we suck, buy us”.
