I had an idea
I think an online wargame campaign tool would be awesome. You could select what kind of map, sci-fi, fantasy, modern; city, rural, etc
Then you could upload battle reports, and pictures and where on the map your battle took place, and it colors the map to show progress and you can program in random events, bonuses etc. to show up based on what you've captured or lost, or just random events like weather.
There could be a timeline view, where you can see how the war progressed, and you can share the page so other people can view it or read the stories and you could put up notable units, etc
I'm curious what others think of this, or if there might even be something like this out there already.
