I would like to suggest Plain of Rusty Nails v4. Advantages:
- it is a wraparound map, as requested, which prevents the weird dynamics that can happen if someone gets a corner to themselves
- Calahan has made it a personal crusade to correct the game, and by v4 it is a safe bet that it has few if any bugs left
- fixed starts, so no-one should start in a truly awful situation
I got stomped on this map playing T'ien C'hi, and can vouch that it is a good map to play on :-)
It does however have a limit of 10 land plus 1 sea. At the moment we've got 8 land plus 1 sea, so if we go with this map we could take two more players and then we'd be full.
Edit: Sorry, forgot the link to the map. It can be found here (v4 at the bottom of the thread):
Plane of Rusty Nails
It is already up on the llamaserver (with v1, 2, and 3 ...)
