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.
Horizon is my answer too. I was expecting an open world that felt alive, but instead it was a jam-packed theme park. You don’t hunt, you go to the right exhibit and kill everything within it. The entire herd is within a 50 meter radius, go nuts. Go away and come back later and it’ll be full again, exactly where it says so on the map, jammed between other points of interest with extensive, contrived looking plarforming challenges connecting it all. It’s like a zoo and a vending machine had a baby but we’re supposed believe it’s a big open natural world. Great concept, garbage execution. I felt like Bobby Hill hunting at La Grunta.
Lol, I enjoyed the game overall but that really is a perfect description of it’s biggest problem. It could have been so much more if they had been willing to take a risk and make it a little less game-y.
