Minetest is kind of a unique experiment in how modular a voxel game can be with mods. It's pretty cool. You just visit another server and it downloads and sets up all of the server's mods. You have dependencies and stuff so not every mod has to reinvent the wheel. Much better experience than minecraft modding.
Minetest should lean into this and make the core gamemode more different than minecraft. Change up the artstyle, and make the physics feel better.
