May I ask for version suitable for small tiles (trident, isohex etc)? (maybe just one wind turbine instead of grid)?
Something like this?
I once tried to play Europe-1900 against AIs, took Montenegro and made a turn, but on my old notebook the server likely hanged from overload, I could not wait until AIs go.
That's probably the only sane way to go forward in getting these included to freeciv. Since there was no response in a year, I started doing this myself (for amplio2 units at first).
