And with how "boring" this run is (I'm not saying that sarcastically, you have to skip over the grinding sections while watching) imagine a few hours of just menuing to get a complete living dex (and that would include every gen I-III mon) and then just doing a regular playthrough. I would also think any 14h+ run would be boring (the longest TAS here is [3386] PSX TOCA Touring Car Championship "max points" by Noxxa in 10:37:18.72).
The most interesting thing about this run to me is the pickup abuse. Maybe a more "exciting" run would be the challenge in Ruby/Saphire since pickup doesn't depend on levels, so you don't need to initially grind up a zigzagoon to level 21 before you start collecting rare candies. I think that run could easily be sub 10 hours, maybe even sub 9.
Personally (completely biased), I think it should be published since it'll be the longest TAS by a wide margin.
