Free to play.. a Massive Multiplayer Online Real Time Strategy, comes across as a Warcraft III clone, but with persistant multiplayer capabilities. From the brief play session I had, it was interesting to try and get a grasp on your unit types, but the game seems in desperate need of a decent tutorial. You spend time just wandering (very slowly, I might add) around barren environment, looking for a city to go into (as the start up blurb suggests). But once there, theres no easy instructions into getting established, and the normal well trodden RTS routes, seem all but a distant memory. So it does drop you in deep, without much of a clue what to do. Could be of interest to some RTS types looking to see how the genre can be moulded into a persistant world setting.
