I would like to play a Serious Sam-like campaign. The truth is that the community may not like its monotonity. It is my experience that if you want to release a campaign that you want the community to like, you only need a good, profound story with some characters. Designing the missions can be worse than TERRIBLE, the campaign would still be favoured. Take Derelict for example, it has more bugs in one mission than the FS main campaign combined and multiplied with 3.5. It is still a favoured campaign just because it's story is interesting.
If you write a good plot for it, while keeping the "kill everything"-type missions, you may release a campaign approved by the community.
How much experience do you have in FREDding anyway? Newcomers often make the mistake of starting to do a very ambitious campaign but never finish it. If you do think you will finish both your campaigns, go ahead.
We just haven't gotten around to this, is all.
I personally think the idea of massive battles is a little... boring, but if you do it right, like one of the Singleplayer gauntlets, I could go for it as an add-on to another campaign.
As far as I understood the first post, he does not mention making Battle of Endor-type missions, only ones in which two destroyers fight.
