60fps is not plenty. You have never used higher have you? Low-end hardware these days is ridiculously powerful compared to what it used to be. Don't let poor optimisation in games condition you to thinking otherwise, they could all be running a lot better.
Anything with lots of camera panning is an objectively nicer experience at 120fps or higher.
This is so incorrect though. Nobody is expecting every game to run on every system at 4K@120Hz. CS has more fidelity and higher framerate than Cities, Rainbow Six Siege has even more fidelity and even more framerate than the both of them (talking like 600+ fps). Cities bottleneck should be CPU as it was in the first game. It should run very well to begin with and slow down the bigger and bigger the city gets, but that's not the case, it runs like ass from the get go. They built it from scratch, which is the best time to make sure it is performant during development, but in most cases devs seem to rush for feature complete instead, especially in the current environment of consumers accepting half-baked games.
It's not entitlement to expect more and it makes no sense to defend lackluster performance in games, if you don't care then just carry on enjoying it and let others ask for better. Again 1080p@120Hz is hardly an ask these days, any GPU/CPU from the last 8 years can handle that shit perfectly fine, hell even mobiles can run that now.
Games should be built to run well on today's hardware, not built to let future hardware take over. Incentivizing upgrades is just going to create more e-waste.
