Having played so many games already, it's honestly not a test of my skills or remotely a learning experience.
The majority of single player games, I just watch people play them on youtube.
They got the high end GPUs, and they do all the walking / grinding .. You watch the eye candy .. They perform the minimum wage laborious tasks. Win-Win, and you don't even need to buy 1080Ti..
