These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
What Could Have Been - It was supposed to be a full-length series, but production was snagged due to staff disputes and was ultimately canned. Then it was decided that what was already made would be made into a movie instead, so we get treated to the a highly condensed version of what was supposed to have been the first quarter of a fifty episode show. Made even more "what could" when looking at Crossbone Gundam.
A MSV release showed some planned upgrades to the F91, among which were one that gave it 4 VSBR rifles, pretty overkill considering the effect it had with just 2, and another take on the long line of "Heavy Weapons Systems" variants of Gundams which seems to be shorthand for "put as many guns and missile launchers on it has the frame can handle without killing performance too badly".
