Here's an interesting project: https://github.com/openwar/openwar
The blog: http://blog.openwar.org
The app: https://itunes.apple.com/us/app/samurai ... 16628?mt=8
Might be fun to mod this with Myth units...the interface is pretty nice, there's no resource building, and it has one thing other RTTs don't--some units are less loyal than others, and if overwhelmed, they may just flee the battle.
