The mission design started to drag on me once the Shivan arc started, and the cookie-cutter escort missions were definitely some of the worst parts. I despise cookie-cutter escort missions in general, and The Aftermath has a fatal case of escort mission syndrome. I disliked them enough that I started just cheating through them. If I wanted to experience sheer, mind-numbing tedium, I'd do something productive with my life, rather than play a long FS campaign. :P
This campaign was going for an 'epic' atmosphere. With the massive wings of enemy fighters, and some cool mission ideas, it definitely had potential. Sometimes, you get to command, and even fly, capships; those were among the better missions, IMO. But the largely cookie-cutter gameplay killed the experience, the campaign's rife with technical errors, and the sheer lack of attention to detail displayed throughout really bugged me. The unintentional hilarity dies down once you hit the Shivan arc, to be replaced with sheer tedium. I gave up shortly before the end.
In one mission, you have to protect a WiH lunar installation [which is supposed to be a space station, but isn't even re-titled] from Shivan attack. Probably because of moment-of-inertia troubles, the station spins around at high speeds when hit, killing both ally and enemy forces which fall victim to the Whirling Moonbase of Death.
