I'm curious what you guys wanted to play and disappointed. For instance I hate BG3 but I expected it to be exactly how it turned out so I can't be disappointed in it.
My top disappointment was Dark Envoy, it's an RPG made by Event Horizon the guys that did Tower of Time, I like Tower of Time and I recommend it but Dark Envoy is just boring. The story is uninteresting and predictable, dialogue is just awful, it's the equivalent of punishing high school students to do a play they don't want to and are given the barebones of a play. Combat is repetitive and the game is very easy on hard. Except graphics Tower of Time is miles ahead Dark Envoy. The pros, the game is not woke.
Another disappointment was Total War: Warhammer 3, It came out in 2022 but I only played it last year. I did not complete the main campaign and I can't say I like the new factions or the new siege combat. I think is a step down from 2.
Forza Motorsport I suppose, because it's the only game I've ever moved on from because I just can't get it to run on my PC well enough to play. I'm not the typical PC gamer that counts every frame and pixel and goes into an unstoppable rage at a single moment of imperfection. I have low standards and still it was that bad.
Albeit, I wasn't that high on the game to begin with. The only other 2023 release I can think of I played was The Outlast Trials, which I thought was excellent.
