Poor story ending and bad Acting (except Kane), great game play and new game play mode!
I will not spoil the story, but the first act was not as solid as I would have liked, the 2nd act was amazing, and the third act was in between. The ending of the story means we will be seeing yet another expansion (and it damn well better be soon!).
Speaking on a personal note, if it was not for the 'global conquest' mode I would have felt entirely ripped off by this game. I am EXTREMELY glad that they seperated the global conquest mode from the main story, but it wouldn't hurt.
In global conquest mode you are stuck with your starting bases being 'vanilla' GDI/Nod/Scrin, and only y our expansion bases may be the new factions, something I hope they change in an upcoming patch.
