HTML5 Massively-Multiplayer Real-time Strategy. Play for Free. Carve your empire, Change the world!
Speaking as someone who has played this for a while, as well as Evony, Tribal Wars, Ogame and many other free strategy games, Illyriad isn't just unique because it has a certain feature not commonly found, but because of the spread of features that, although maybe not revolutionary by themselves, together create something wonderfull. I highly recommend this game! (contact me ingame as §teadfast Shield for tips and resources)
