Love your ideas

It's not realistic in an MMO though, since there's so many PCs with potentially unique animations, glamours etc going on. With UE5 though, nr of polygons would be irrelevant, but not sure how that translate to characters. But in general with MMOs, you need to tone down everything to a minimum so more ppl can play it with lower-end Systems. 1.0 was severely unplayable for me. I think my graphics card broke because of 1.0. I tried to use max settings to take screenshots during last days, but i got like 1 frame/min or such.
It would be so awesome to see these things though.
It's a bit funny though, how we marvel more at game geometry than what we see IRL, esp in VR

it's like seeing everything for the first time, again.
