For the map for this mod, all the resources should be removed, because the resources and bonuses in the mod would be particular period-specific ones, the normal resources (oil, iron, coal, etc.) wouldn't show up in this era and so shouldn't be included, and a few other resources (sheep, cows) would probably be handled differently.
We don't have a list of resources yet. Fish, crayfish, greenstone, stone seem possible.
Sheep, cows and wheat make sense for Europeans, but not for Maori until very late. Similarly Kauri and Kauri gum.
But most other "normal" resources don't really make much sense.
Any ideas?
I think that a map should basically have the south island cut off in the SW corner of the map, so basically the map would go as far south as Banks peninsula on the east coast and greymouth/hokitika on the west coast. No need for anything south of that.
Geologically accurate is probably ok as a start, but I worry a little that the important areas won't be big enough, and that too much space will be taken up by various unproductive hill country blocks (Tararuas, etc.) and that there might not be enough land to make auckland/bay of islands into productive/important areas.
Another thing to think about is: what should the level of forest cover be? Do we want to strive for something semi-accurate, historically? I'm not sure what that would be for ~1800 start. AFAIK Canterbury had already been largely burned off by Maori by then, but most of the rest of the country is still probably forested. But that might not be much fun to play in.
[A thought; even though sheep/cows are bonus resources rather than luxuries or strategic resources, is it possible to have them tech-linked? That is, they could still be there, but they'd be revealed only by a tech that belonged to the European player, so the Europeans could still build pasture resources but the Maori players couldn't - or couldn't without some high level tech. Can a resource be revealed by either of two resources; so sheep could be revealed by a generic resource that the British player starts with *and* by a high-end tech available to Maori players? Livestock resources should be very valuable.]
