I just finished playing a few rounds of this game. It reminds me a lot of Fire Emblem, except it's multiplayer. From what I can tell so far there's a lot of depth and strategy to this game. It's free to play with 2 pre-built armies (one light and one dark). Optionally you can buy 'Rune Packs' if you want to create a custom army. I think it just went live this month, and there are some friendly players willing to show us newbies the ropes.
