That is true, I prefer inside-out tracking as well for the same reason. Though for sims I think you’d only need to set one base station up, and I doubt they’re as finicky as the OG Rift sensors.
The inside-out tracking on the G2 is not great compared to the Rift S, however that’s mainly an issue with the tracked controllers. With sims it wouldn’t matter so much.
Note that I still use my G2 over my Rift S, even for tracked controller games like No Man’s Sky. Lucky the image and audio quality is so much better, because it feels like a bit of a downgrade everywhere else (comfort, tracking, controllers, software). :)
