Excellent MMO real time game.
Build an empire, create armies. Choose option for pvp mode or not.
Quick tip for getting started - build farms (for food), cottages (for people to get gold) and mines for mithril. Build some warehouses to store it in while you're offline, it'll just keep on going. Once you've got a decent steady supply, train some troops and start growing your empire by fighting monsters and other players.
Great game - it really is the best MMO I've found on WP, great graphics, fast and easy to play, but plenty of chances to get sophisticated later on.
Best of all - it's free still while it's in beta, and even now, not a lot wrong with it. Devs are pretty active, using community to drive development, even voting for upgrade features.
If you find this useful, join the game and use refer code CA05 - that'll give you (and me) a joining bonus of an extra 100 gems which help you cast magic and grow cities.
