There are actually quite a few innovative games this generation with brilliant storytelling. But yes, there's very little advancement in gameplay or immersion.
You really don't need a GTX 1080 Ti. It depends on your screen resolution, firstly. A vast majority still game at 1920x1080. All you need to get to 60 fps on that is a RX 570 or GTX 1060. While the miners have ruined the markets temporarily, RX 570 is a $180 graphics card. CPU - Ryzen 3 or Core i3 is good enough - $120 or so each. So it's actually possible to build a $500 PC for 1080p 60 fps gaming. For 1440p, a GTX 1070 or RX Vega 56 is quite good enough. It's only for 4K and high frame rate gaming and all settings maxed out where a GTX 1080 Ti becomes necessary, but that's pretty much an extremely niche thing at this point. With Vega 56 (which I use) even 4K on a Freesync monitor is achievable with minor tweaks to settings which you'll never notice.
Sure, Ubisoft has had a reputation for buggy games, but it's a fair comparison for frame rates. Unity runs like shit. Syndicate is not perfect, but it mostly holds 30 fps at least.
