If your sims do something autonomously without rolling a want for it, you don't have to worry. If there isn't, use your judgment (for example, changing radio stations and switching tracks on the stereo do not affect gameplay for the sims themselves). If it is unclear whether you can issue a command or not, ask yourself if there is a want relating to it in the game. This means that you may not direct them or buy items unless it is to fulfill a want (exceptions follow). This challenge is run by the wants of your sims. Some interactions are included in all expansion packs after the one they were introduced in, so I recommend to read through and keep the whole ruleset if you attempt this challenge. I have categorized the rules per expansion packs to make sure I don't miss anything (and to make it easier to distinguish between rules if the attempter doesn't have them all). University or a later expansion pack is required to have Lifetime Wants (LTW). Inspired by and sort of converted from the Wishacy/'All My Wishes' challenge for Sims 3 by buckeygirl80. I'll try to remember to bump it for each edit. This ruleset is still a work in progress, so please check back every now and then for eventual rule clarications and changes.
