But... I can see the inside of my ship.
Indeed - and in VR I can move around a little bit and crawl around the floor and squee in delight at all the little details that FD included in the various ships. And later defidelitised. And in some cases removed altogether
But there is absolutely zero gameplay there.
That's not a bad thing though, because there are absolutely zero gameplay mechanics implemented for such micro-scale environs. FD could very well come up with something fun, but that'd need an entirely separate locomotor mechanic and separation of "self" from "presense" and all that assosciated ship interaction.
CI-G have gone about it from the exactly opposite direction. Not only have they mitigated any possible issues by the simple expedient of not including VR; there's barely any shipboard gameplay possibilities, and their much vaunted "you'll run around in the BDSSE greatest game ever, and change fuses mid-battle and mix drinks for VIP's" has been neatly sidestepped by not having any fuses, drinks, VIP's, or actual game
