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 didn’t work any harder building up a skill tree in Morrowind or oblivion then Skyrim, I’m usually just walking around talking to people or looking at the forests instead of thinking about the skills at all. Playstyles.
When you mentioned fallout, do you mean that the newer fallout games were easier for you to navigate the skill tree as well?
Kinda. Fallout 4’s levelling system (and decisions) is dramatically easier than earlier games. I’m a bit rustier, but I early-quit my last New Vegas playthrough over it.
