Thanks for the tips! i ended up using the simblender( i really like that tree more and more every time i use it!) and only summoning some people, since my system is not that fast, and i do not want to risk it crashing by using the boolprop mailbox trick and summoning too many sims at once.

and yes, i was looking for Riverblossom hills. thanks. my game is in dutch, and while i know most names in English, i do not know all of them.
