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.
Gran Turismo 7. Only 4 high payout races to earn money. All my friends still play on Gran Turismo Sport because boost doesn’t work in multiplayer. They updated the missions awhile back called the human comedy where if you had it on hard mode it was easy and easy mode was down right impossible. I will never purchase pre-order or digital ever again.
