Zero hour is one of the best ‘RTS’ games I have played in my life (if not the best!) ZH is like the icing on the cake, as with the new implimentation of the new generals; comes a vast amount of new strategies and tactics to overcome the new sides.
Learning every tactic your General has to offer is half the fun of the game and it makes me wonder why I would want to play any game other than a RTS such as this. However Online-play is pretty much required for full enjoyment of the game.
Excellent game, highest recommendations.
