I don't think 100% is very practical for a FF game that doesn't keep track of %. There are just too many ways to define 100% in a game like this. Not to mention that it would probably be way too long to watch, in my opinion.
Yeah, 8+ hours is long enough anyway. If you really, REALLY wanted to go for that then you would have to define your own category e.g. "All-GFs" I don't know what the prevailing opinion is regarding challenge speedruns. Whereas some of them would be quite interesting to watch as they make the game harder, and therefore more impressive imo, an all-GF game would just make it longer, not harder. (Fighting 20 tonberrys and getting all the Doomtrain ingredients spring to mind as being quite long-winded...)
I'd be interested to see what you can make out of an Omega Badge run though!
