So my founder finally was able to eat ambrosia, and I chose a cooking sim first mostly because I thought that everyone else would leave behind more expensive things, and they would be able to contribute 10 items. I had him cook up the ambrosia, and to my surprise, it sells for over 3000 simoleons! That was the first time I ever had a sim cook that stuff up.
Poor guy, I made him dig up so many rocks to see which 8 metals, crystals, fossils, or mysims trophies I could find to make the highest museum value.
