I'd like to see some smart resource node distribution during map generation... (this should have been done for the launch of the game, but to make good, do it for 1.1 and I'll be a happy gamer.)
Materials seems to be wood and other non-metallic production materials so it makes sense to me to place these node near or in Forrests.
Metal nodes should mostly be placed in or near mountains mostly and to some lesser extent hills. (Where mines usually get built)
Quarries inear Hills and Mountains.
Crystal in caves , caves could be in mountains, Hills, shore lines, and im not that familiar with deserts and plains so I don't know if those make sense.
Fertile land in nondesert plains, in the fringe between swamp and plains or swamp and hills or swamp and deserts.
Mount nodes - wild mounts need food so it makes sense to only place mount nodes near were wild mounts could feed on wild growth (ie. Fertile nodes)
Shards, Tech, arcane, Diplo Capital nodes I consider to be ruins that get rehabilitated, so that could be placed without terrain restriction.
I don't know does any of this make sense to anyone else?
Lastly please stop clumping nodes and distribute them more which by itself would encourage more conflict. Today in the real world, most conflict between nations is more about natural resources than any difference in ideological belief systems, mostly for propaganda purpose those beliefs are spouted to sell the moral value of attacking someone to take something but the reason to attack is really that something that is taken.
