I would love two mods regarding festivals, so hit me up if they already exist !
I wish buy&wear the festival t-shirt would create a new outfit in the current category, rather than replace the one you're wearing. Same for the curry contest winner t-shirt, this one is worse since I don't even choose to have the sims wear it.
I would also love if geekcon could have more teens (and even kids) in the audience, mine is always full of adults and elders with maybe one teen and 2 young adults, and it's disappointing. I know married couples are more likely to show up at the romance festival, so I guess there is some sort of filtering for festivals already.
