That guy is a douche. There is a point to the single player portion. They build a half-ass set of worlds and objectives and the ONLY purpose in playing it is to get used to the worlds, the weapons, and the vehicles. That is the ONLY purpose. Beyond that, no one gives a shit about it. Everyone is WELL aware of the restrictions of single player/campaigns in modern FPS. To expect more is just pointless. The only thing they care about is multi-player but everyone bitches when a company even mentions releasing a game that is multi-player only.
