Really hope going forward we do not get less single player experiences. I like mainly SP games and if they made less and less of those I would slowly stop upgrading my GPU. Might get to a stage where I just upgrade a lot less, which is already starting to happen anyway.
We have not had a game like Crysis which pushed things forward for a long time. The only reason I upgrade now is for 4K and well I suppose I like new cards. Nvidia should sponsors Crytek to make a new reboot of Crysis that is a PC exclusive which makes Titans crawl to their knees maybe. They could have graphics options in settings where they make it clear it is for future hardware, so people who use them and get 20fps do not cry so hard.
Currently I have a nice balance between the Nintendo Switch and PC. My Mario pre-order should be here soon which will keep me happy for some time
