But... I have fun doing it? I like making things. And i think having the hexagon maps would be super cool. But i will agree with you on the fact that it'll be a pain in the ass to setup the game if i wanted to prepare the landscape and map. Just for the record this is what i want to do for myself.
My friends will probably do some premade map or make something on roll20 and print out, or one of the resources you linked.
Players ALWAYS ruin your preparations. So i can understand why you feel that way. Ive lost count how many stories i read online where DMs die a little inside because of the stuff their players do is always outside of their expectations.
