Noone said it was empty. Noone said there wasn't a lot of 'stuff' in NMS. What many of us are saying is that all that stuff doesn't make the game fun.

Different people find different things fun. I've never been grabbed by multiplayer FPS (I never git gud) - or souls-likes (same). I do sometimes get sucked into some Bethesda games but I need to get over the initial hump. I had a serious Minecraft problem (solo play - not groups) and had a big Beat Saber phase. I still play OG Doom but never liked Quake. I usually hate games with narratives except when I don't. Journey nearly made me weep with joy and sadness but I don't tend to go for slow, arty games in general... And - in general I want to like games, find them fascinating as a medium - but find most of them tedious when I sit down to play.
