Family, and rotational player here. With a bit of sandbox. I play families with non-aging families with babies, children, toddlers (Ts2 and Ts3 only, obviously), teen, and young adult/adult parents (single parents; two parents; LGBT families, etc). I age up sims when I feel ready to do so.
I love the kids in all of the sims games, even sims1. Sims 4 kids are cute, but they need more play interactions like previous games. However, I don't like kids having goals /aspirations in sims4; I want my kids to be kids before such specific life goals start coming in. I would like more interactions for these little cuties.
Teens, meh. Don't like them in ts4. I preferred them in ts3. Toddlers and baby objects are obviously the sticking point, so my type of family play is restricted.
I want my babies to be free--even if they're laid on the ground sometimes, lol. ;)
Sandbox hampered by specific career goals and dating goals, etc, in ts4. I like it when I can turn off said goals, but careers can't get much money if I don't follow those goals, it seems like so far. Can this be tweaked perhaps? :/
Culling issue and random romantic interests are hampering all of my playstyles (rotational and family, in particular) in ts4.
