Movement less war games

I realised that in my pacific war game, what made the game very fiddly was the fact that troops needed to move on the board. But if there was no troop movement, it would remove many of the problems I have.

So I was wondering if people knew any movement less war games that I could use for inspiration.

My first idea would be that adjacency of hexes determines who can attack what. The more adjacent hex you have to the target the better the bonus. The units by themselves would come from a central supply for the whole nation. Which means that when you lose troops, you remove troops from the supply. It creates some problems:

First, there must be a way to win without killing everybody, else you will need to kill all the soldiers in a nation to capture a single base.

Second, I thought it would be more interesting to have a certain form to troop distribution over the map.

So I though of having key bases that can supply a certain radius of base. Each key base would have it's own supply in troops and if a base in it's control area get attacked, it can send immediately a land troop to defend. Troops can move from key bases to another between turns if the bases are in the supply net.

A problem is that I need enough key base to cover the whole map, else I could end up in a situation where a certain area of the map cannot be covered which prevent the player from progressing. (For example, if you land on the USA west coast and there is no key base in the middle of the US, the troop will not be able to reach the east side.)

So the solution would be to have to option to build a head quarter anywhere you want that will make the location work as a key base. It will make the game more flexible and avoid dead locks I could not predict.

What do you think?
