(plus even more stuff mods which do not live on CDB or have died with MT 0.4.x, such as galvorn & mithril in LOTT; besides, has anyone ever considered a more specific name like "equipment" rather than the insanely generic "stuff"?)
This is boring. It already was boring in Minetest Game - the tools don't differ except in their stats. Generally, the better the tier, the better the stats. "Stuff" mods just add yet another boring & redundant tier. The only notable exception here is LandarVargan's Lava Stuff, which has special effects (e.g. the lava pickaxe already "cooks" everything you dig with it like the MTG furnace).
