[The Fifth Horseman]

For me it also turned out different from the usual RTS pattern, since the resource management is drastically different (Resource Points are earned by claiming locations on the map, thus neccessitating an agressive mode of expansion from the get-go).

After a while it got somewhat bland. While it's nice in multiplayer, those who simply don't have net access will not enjoy it half as much as the others. The single player mode offers only one campaign and a bunch of pre-made maps for one-off battles (there are no stand-alone scenarios).

I heard the expansion packs (Winter Assault & Dark Crusade) improve that a bit, though didn't have an opportunity to find out myself yet.
