(eg. like classicgen or random.txt)
Been working on this then got bored because couldn't get people to host it...
You can go play Greece and Pyspades+ on "SEXY SERVER FOR SEXY PEOPLE" at aos://1436491696:32887 if you use 0.75 or "DANY0s for sexy people" at aos://1436491696:33887 for 0.76 folks. (edit: the staging master server looked down, so I turned the 0.76 server off)

Then just add water, eh, I mean add the maps to the rotation.
(Screenshots are old and not represent the current state apart from visual appearance)
Greece:

Description:
Greece Mediterranean islands area - like landscape with wineries, ports, pre-generated bunkers, trees, bushes, ports, buoys and a big spawn mountain on one side ( also a logo on the bottom left part of the map)


and parthenon-like temples, bushes, more trees, boats, pre-generated bunkers, buoys and a large spawn mountain again on the other side



Pyspades+:

Description:
Attempt at reconstruction of the feel and improvment the map "pyspades". Islands range from medium to large with islands guaranteed to be in the spawn area and the middle.

A typical generated map.

Exceptionally big island.

An older screenshot of a random seed.
ClassicgenTrees:

Description:
The gen map with ugly trees. If you wish to make better trees, use the shipped qbuild plugin to record some in-game. (use /qbrecord colored or /qbcopy colored)

Thanks to Triplefox on advice on the MapMaker API, infogulch for making avx loading script and TheGrandmaster for advice on the Pyspades+ map.
