In my opinion, this game could be like this: 2 teams against eachother with the objective to destroy the enemy harbor, but it would be a real war with a lot of ships, air planes, towers on islands to protect those harbors and to make a difficulty in game. Here is a resume:

2 teams against themselves;
AI ships and towers with guns (ships and towers controled by the artificial intelligence);
2 Harbors working as "main base" (it is just to know which team is winning, by looking its "health");
The objective is to destroy the enemy Harbor and protect yours.

Please see if this game could be developed by TNF.
