most vr games are in a bad place due to restraints put on them:

• in order to reduce motion sickness they avoid immersive movement. ofc people still get motion sickness anyway
• the vr market is tiny and thus budgets are ass garbage level

a modded port is unapologetic. it thrashes you around. but its so hard to set up people want official ports... those are filled with bugs to hell (looking at Bethesda here) and need to be fixed by mods, which takes a lot of tedious effort with errors yet again
