Guess it must be an age thing, as I'm the same to a degree. The games that I've literally lost myself in over the last 15 years, are limited to Bioshock, Far Cry 2 and 3, Fallout 3, Assassin's Creed Brotherhood and Blackflag, Skyrim, and GTA IV and V.
I've dipped in and out of other games of course, but none have held me for hundreds of hours like the aforementioned.
I thought I'd return to true immersion with RDR2, but as enjoyable as I found it, I haven't completed it yet, and haven't been back to it for quite a few months.
Same story with Death Stranding...played that a LOT but suddenly stopped playing it back in September and not been back to it since.
Many other things in life of course, and I'm sure there will be future games that will hold my attention.
