I've been playing around in nraas Retuner and found some things that I found interesting. First of all, I went to retuner and using nraas/Retuner/settings/general/social interactions, you can tune out scolding/punishment and you can tune out the "berate intelligence" and a number of other interactions which can be seen.
Next, I started to explore and disabled alien abductions (nraas/retuner/settings/general/by tuneable/sims3.gameplay.actorsystems/AlienUtils/kAbductionBaseChance 0, kAbductionsMaxSpaceRockBonus 0, then below "AbductionReactions," is kAbductionSpaceRockBonus 0, next is kAbductionTelescopeBonus 0. Click the small x at the bottom to return to menu. 15 lines down after this is "kAlienHouseholdVisitChanceActive and I put in 50 b/c I want aliens to visit. If you do not want aliens to visit, the put in 0. In my current challenge, I'm only allowed to marry a npc or a townie. The aliens count as npc's so if I can get her to be acquainted and romantically involved with one, then she can marry him.
Next, on appliances, I get tired of food spoiling so fast in the cheap fridge and so I have the "buyable Culinary reward" and usually get the minus 1 Kelvin fridge in buydebug/miscellaneous section. However, if your sims don't have enough money to buy that fridge (it is expensive), then you can use retuner again to prevent all food spoilage.
To do this go to: nraas/retuner/settings/general/sims3.gameplay.objects.appliances then under fridge, there is cheap, moderate, and expensive, and reward. When you click on any one of the cheap, moderate, or expensive fridges, click on the last line "kFridgeTuning/SpoilageMultiplier and set that to -1. When you look at the reward fridge, that is the spoilage setting.
If you want to totally disable bee attack and sting chance, go to nraas/retuner/settings/general/tuneable by xml/sims3.objects.insects/beekeepingbox/kbeeattackbonus and click on "list." Set all three to 0. Click on the small x and then go to kbeeattackchances and set all three again to 0. Click on the small x and go to the next one down which is kbeestingchances and set all 3 to 0 again. There is also the chance to harvest wax, kcleanlinessdecrementpersimhour, and 6 lines below that is khoneyproductiontimeinsimhours and I put mine to 6 since I want more honey. This will make it almost a full time job though so be aware of that.
These are just some of the retuner settings. There are many others to explore. For instance on objects, some of them have pregnant sims disabled. Whenever you run into that, just go to retuner/settings/general/by object and then look for the object and set pregnant sims to true. Have Fun!
