In Age of Time, dynamite is the only way to damage trees and, by extension, get the wood they drop. Ore rocks, meanwhile, can be damaged and destroyed by anything, even a single sword swing, and will always drop ore, making use of dynamite a waste. Meanwhile in real life, dynamite has been used for mining (IE ore collection) since its invention, and would be pretty much useless in trying to get usable planks of wood from a tree. Oh, and good luck trying to pulverize a boulder with a rusty longsword.
All I can say is, what the hell, Badspot? Was this a conscious decision? Were you high when you made it? Or did you just not care?
