Gamespot,what´s your problem?
new music, and 12 new campaing missions.
For all this, a 5?
Of course, the new units really need some balance before (except the URSS Units, for me they are just perfectly balanced), especially the Giga Fortress. It´s easy winning a game concentrating all your money to grab one in less than ten minutes.
Of course, the midless mass-fabrication units by the AI in the single-player make impossible to win if a match lasts more than 20-30 minutes, since it´s impossible for a non-machine opponent to spit out the same bunch of units to counter, making each match too short.
Of course, The new campaing really takes it too hard sometimes, making it a bit frustrating to reload the same mission over and over again.
Nothing that a good patch can´t solve. And even if that patch didn´t come out, still, its a really great experience playing the game,I really think that the early game had not enought units. the new ones it´s just what C&C needed to be almost perfect.
For all C&C Games, this is the best one. It´s the only one that reminds me of the unique gameplay of Starcraft. This C&C expansions it´s an evolved version of that kind of gameplay that I never found in any other RTS game. Despite of it´s flaws, it´s marvelous.
