I am most excited for the off-the-grid lot trait, I think.
Cooking: barbecues (the barrel one from JA), the coolers and campfires from OR, the new cooking pit. I plan to avoid fridges unless they are updated to look like cabinets or shelves or otherwise made more low-tech
Lights: candles
Entertainment: books, card tables, musical instruments like the violin and guitar, the easel, toys. Lots of choices there.
Toilet: toilet bush. I wish they'd add an outhouse or an earth toilet.
Hygiene: shower in the rain (came with Seasons), waterfall; I am surprised to hear that swimming improves hygiene, because that wasn't the case in pools, but, if true, that will make it easy to keep sims clean. I wish they'd added a hot springs hot tub.
Energy: beds, tents. They need to bring back sleeping bags and find a way to make coffee and tea without appliances.
Something was said about certain objects being updated to work off-the-grid in the next patch. Maybe that means outdoor showers, short-wave radios, plumbing-free toilets, oil lamps, pantries instead of fridges, etc. I hope so; more options are always good.
