I use lots of Twallans mods but one i've recently added which I think is amazing is Traveller, one of my sims is doing the mixology LTW and when I realised I wouldn't be able to do all the mixology challenges in Riverview I was dissapointed, no way could I add enough clubs to learn all those drinks.
Well as usual Twallan to the rescue
Traveller has enabled me to send my sims to Bridgeport on vacation so they can visit the clubs and also make use of the subway for tips. Awesome!
I also added Relativity recently as well, so far it's great although their sleep patterns are a bit out of sync till I get used to it, but I can do so much more in a sim day now.
I don't think I could play without Twallans mods now, I did recently for a challenge and it just made me appreciate them even more. I love the story progression, master controller and woohooer mods, I never really like directing my sims to woohoo, it feels unatural and forced, and the risky one makes pregnancy a bit more spontaneous and exciting so I usually put that on when they both want a child rather than use try for baby.
I haven't noticed them buying cribs or furniture for the house but I have notice them getting items that will go in they're inventories like strollers, cars, bicycles, and motorcycles.
Canes seem to be the favourite thing in my games lately, i'm always being harrased by the elderly
One thing I was curious about. If a family has a child and they live in a house that doesn't have a crib, does the game automatically purchase and place one in the house for them? Or does it force them to move to a cribbed house? Also, does the mod and/or game itself have them buy nicer things from time to time?
Rigorous Home Inspection under the lots menu checks for things like cribs, double beds and career objects when moving sims, I think it will also force moves, I usually turn it off but I do remember getting notices in the past along the lines of conditons in the house are unsuitable and the family may be forced to move.
