Indeed, there is much truth in what you say. My conversion was actually a modification of somebody elses conversion (I fixed a bunch of bugs, particularly in the loop missions.)
The idea of breaking up the campaign into small batches is an excellent idea, but that would require a just a little bit more work on my part, and right now I have not the time to make the necessary changes.
I have played your conversions, Centanu, and they are excellent. Needless to say, although I can see how the main FS2 campaign missions could be so modified to provide some real challenges, again I have not the time. Oh well, one mission at a time...
