The only collecting my Sims have done was during my Legacy Challenge game. They collected to keep themselves alive, and the lights on. LOL Other than that, I like my Sims' kids Child and Teen to have private journals. This helps them cope with their emotions and adds to their Values. Sometimes, I'll have a Sim garden. In my TEST save (started after the patch took out some of the mods I find necessary to play) I had one of the Sim Teens garden. She found a Cowplant seed in the Rare Seed packet. Dern monster needs to be uprooted! LOL
