There's not all that much really complicated, FRED-wise. For example:
In the 'disarm three Sathanas' mission, it doesn't matter how many beam cannon you destroy, or if you fully disarm any Sath. The results are the same: Command briefing telling you how many Collossi you lost. If he had been a real pro, he could have carried over results and let you play the mission where you blow up those three.
That sort of thing happens a lot: He can't figure out how to do something really cool, so he throws 50 fighters at you and calls it a mission.
On the plus side, I learned quite a bit about FREDding from this campaign. Much of which I plan to implement in the ol' dodgy mod.
