I've dipped into Realities a few times in my VR exploits, and it is definitely one of the most interesting early entries for VR sightseeing. I do wish it had grown as a platform, despite its flaws

Luckily it did, a bit. It added some additional locales to explore, most of them varied and fairly interesting. European architecture, canadian landscapes, and my most favorite due to some excellent narration and atmospheric designwork was the last german coalmine. Very fascinating stuff, and even with blips in the photogrammetry, you'd be in some breathtakingly realistic scapes.

One other complaint beyond the photogrammetry would be the unevenness from experience to experience. I believe the base realities was created as a way to showcase the promise as a tourism and educational tool, and the further locales were then collaborated with other bodies to produce. Due to the way it wasn't centralized, there's some unevenness with the quality of presentation. For instance, the german coalmine was incredible, so was Death Valley. But one of the chapels, destroyed and vandalized was very cool but with no narration, and some of the others with very little. And whichever canadian partner tried to force a compass gimmick that didn't really work for navigation purposes.

All that being said, it's nice to get out of the house in the 8th pandemic month still and visit some places I might never get to.
