Bizzarre Map Ideas

Just some random ideas to encourage discussion:
Stupid ideas? Probably. Just a stream of concienceness.
Others?
- Territories that if you auto-attack and conquer them, you get to keep your enemy's armies. Would it work? Maybe not as they would always be getting larger.
- Nuetral countries that multiple players can occupy at the same time. But how would you win? I dont know.
- Weather patterns that affect the dice? Similar to the radiation plus/minus is USA-Apocolyse? Maybe they change every round?
- Territories that are infected/possesed/cursed/etc? Meaning that they might give a good bonus but every turn some armies die off?
- Random teleportation/worm hole territories? Every new round some territories armies shuffle about?
- Tides that change dis-allowing attacks at high tide. ie:Brazil cant attack North Africa during high-tide.
- Nukes? Air bombing?
Stupid ideas? Probably. Just a stream of concienceness.
