I'd love to hear what traits you've all been able to discover and how they were triggered? I'll likely try and replicate it as well as see if there are other ways to trigger them. Maybe it's something to do with earning collectibles? I wonder if that was because it's a new skill, or fishing in particular that is considered to be 'adventurous'. I also fish for the first time with a sim and the game prompted to give that Sim the Adventurous trait pretty quickly. I declined the first time but it wasn't long before the game gave me the option to self discover Active again. So far I've seen the Active trait pop up when I used the workout machine. There are traits like Lazy which I imagine would be fairly straightforward, but I'm particularly curious what it would take to gain some less obvious traits like Erratic. I know the pack is still new so not a lot of info is available and the devs might still be tweaking this new feature, still I want to try.
I've seen several posts on here and some traits like Active and Cheerful seems to pop up pretty quickly, but I've yet to see many other trait being gained, both on here and in my own usual gameplay. I want to do some experiments on the self discovery feature to see what it would require to gain every trait that's available in the game.
