I would watch that.

i can tell you what i have found out/read in other Forums. Maybe somebody have an idea how it is possible to realize bigger maps which works. You can get bigger hugh maps you have to go to:

data

rules

ID: Mapsizes

Change big huge map from 100 to 140 and save it.

Why 140 ? Because as far as i have read, the game and/or the moving cursor can not handle a bigger map than 140. All above it, will make the cursor get buggy. that means, from 141 to 200, there will be a certain part of the map, you can not send units or build or send your resource gatherers and so on. And the bigger the map, the bigger the area you can not plat at

For some reason, you can do everything on beach/shore or water, no matter how big the map is.

Maybe that will help somebody to find a solution or a help point for a mod

From 201 to 300, the selecting square for units will also getting buggy in adition.

And all above 300 i would not recommend because at 300 plus, the game will crash.

Thats all so far I hope it helps. I am eager too to see bigger maps.
