I am researching the feasibility of setting up a mapping tool for my alliance in an online game. The game is not based in the real world so I am not interested in the content of the map tools available, just the functionality.
Minimally, I would like the map to display information about where allied cities are located in the world. Ideally, I'd like to be able to display information about desired trades, levels of development, and military actions. All this should be editable by the map users.
I've been looking at the google maps API and it appears that I could use it to serve my ends by using my own map tiles with a custom defined map object and some custom overlays, but it looks like it would be a lot of work to set up.
Is there another tool that would be better suited to this task?
