heres what i think should be added
1. terrain
terrain that can be shaped with tools like roblox studio (paint tool could be added for biomes n shi)
2. vehicles
this would probably be fun to drive around on terriain
3. tools
kinda like gmod where theres thrusters (for vehicles and stuff) that you can play with
4. npcs
self explanatory
5. time manipulation
in bonelab where you can manipulate time
6. weather systems
idk i js feel like this would be cool for some reason like a tornado that you can spawn which effeccts things around it
if these things were added i would def play for hours
