I love how there are games like terminator and assasin but more might be better. Games like capitol were after the territory drop, you would place your home/base. To win you would have to take over a certain amount of capitols.
For two you would have to take over the other persons.
For three you would have to take over one.
For four you would have to take over two.
For five you would have to take over three.
Etc.
For team only your capitols count you can't combine capitols together.
Another idea would be mission. For Example the mission for a classic game might be, gain control of South America and America or gain control of europe. It could go on forever for every different map.
