For me it’s Deus Ex Mankind Divided. I played the original when it was new but barely remember it and I owned shadow war and never got into it.
However Human revolution blew me away. I loved that game so much. I still think about it and actually am making this post because I finally started cyberpunk last night and got human revolution vibes like crazy.
However I bought mankind divided on my birthday when it released. Happened to be right around the same day. I turned it on, walked a few steps and turned it off. For whatever reason I’ve never turned it on again.
Nioh 2. I think I got Nioh for free at some point after Nioh 2 had already released. After 50 hours into it I purchased the sequel because it was so good. After 120 hours I still hadn’t finished the game because I’m a completionist and have to do all the side quests. Then something else came out that I wanted to play so I took a break. That was a couple years ago and I just haven’t felt like relearning it. It didn’t help that the mouse and keyboard controls were terrible, but I can’t play third or first person games with a controller. Wo Long was the latest game by the dev that I tried and it also suffered from terrible controls and I gave up on it after 10 hours.
