Heroes of Gaia is a browser-based 2D isometric strategy game, where you build a persistent kingdom and armies to both defend your land and steal it from other unsuspecting players. The game is currently in an open beta phase right now, but is looking forward to their first major update, entitled Babel, which will implement many of the requests of the player base.

If you think raising and army and conducting RTS combat is your thing, then you should jump on over to their main website and give the game a glance. It's free and run on an item shop, so there's not much to lose except a few minutes of your time.
