I'm going to defend an earlier entry of the Second Great War Part 2. It was in fact epic, in the sense that it was an epic fail. I remember trying to play it way back in the day, most of the missions were broken and wouldn't run at all, not to mention the various things wrong with the design. Perfect example of what not to do.
Um...I've played through SGWP2 a few different times, and the one thing it
doesn't have wrong with it are any show-stopping bugs. Hell, I didn't really come across any noticeable minor glitches, either. Its plot is a mess, its mission design is questionable at best, and its grammar is atrocious, but mechanically, it's a perfectly-playable campaign.
(And I'll still stand by my assertion that it's an immensely-entertaining experience. It's the B-movie of FS2 campaigns.
