The majority of my gaming time is on my Xbox One S, definitely. I really, really like the One S a lot, and am now a Game Pass subscriber and am starting to explore that. I like having one box that lets me play new stuff, old stuff (for my never-ending Mass Effect trilogy/Dragon Age 1/2 runs), and watch Netflix/Hulu/YouTube/etc. all from one place. It literally powers all our TV activity 95% of the time.
Otherwise, I have my Switch, which I love but don’t always use as the “primary” just because of the sheer volume of lengthy stuff I have on the Xbox. I also do some gaming on my Mac Pro via Bootcamp (it’s a 2010 model with an 8GB RX 470 installed), though I find myself preferring to play big narrative-focused stuff like RPGs on the Xbox because I can kick it on the couch instead of at my desk. I prefer stuff like Cities: Skylines on the computer, though.
