Quite a fun RTS. Units aren't completely braindead and can do some basic tasks on their own without needing to constantly babysit them. And despite the amount of different units, only a handful could be considered subpar. Most of them see frequent use in both 1v1 and team games.
The campaign is a great introduction to all the different units and mechanics, though some of the later missions are quite hard, even on easy. Some of the bonus objectives are also quite difficult, thankfully you don't need to complete all of them in order to complete every mission.
Multiplayer is fun, and if you're not comfortable with PvP, co-op lobbies are quite common. The big team games (Teams All Welcome) are quite hectic when there's 10+ players on each side, but are fun.
