One of the things that disappointed me when I found about the Sims 4 traits was that even adults could only have three main traits (not counting reward traits).I thought this was a bit unrealistic as actual adults have many more than three main traits. Also, at this stage you can only add reward traits to a sim, not main ones. So, I looked around in the extracted XML files and found a traits.traits xml that modifies the amount of slots available for each age. I’m not sure if this is something anyone is interested in, but just in case I have made it available.
