I'm on my second full playthrough (having gone back to partial save files on my first run to replay a few options/endings).

First time I focused a lot on yellow social skills with red as a sort of secondary (and had almost no blue haha) and befriended/maxx'ed Marz and Nem. At Vertumnalia, I typically did the talent show during Vertumnalia and won with high creativity.

This time, I maxx'ed Dys, I've done a lot more exploration and focused more on that and have high biology, high perception, and high bravery. At Vertumnalia this time around, I've often been locked out of participating. All the options are greyed out. Is that because I have high rebelliousness? Or do I lack sufficient skills to participate?

It's kind of a moot point now since I'm at year 18 but I was just curious for future runs.

I looked around but can't find a list anywhere of all the options for Vertumnalia with the necessary minimum skills to participate (such as: minimum creativity whatever for the talent show, minimum skill for robotics challenge, etc.). Anyone have this info?
