at the mo after playing 3 or 4 different saves so I've started a new one with the intention of switching between multiple households within the one save.
I find I stick to one career path and usually focus on the sim I created first since they are usually highest skill and that gets a bit boring. If I want to explore different content I find myself torn since I've usually maxed career but can't get the time to do the other stuff I wanna do due to job schedule. Switching to other household members is fine in theory but i go back to main sim without realising :') .
So in the new save, at the moment I have two besties running a bakery / gallery and have got the retail lot to where I want it to be for the most part (with accommodation) and am working towards saving for an apartment to move to (they "live" on an empty home plot).
Once they are sorted and comfortable I will make a new sim to move into town and take a completely different path and get them setup and rinse repeat.
I want to interact my sims with all my past played sims and maybe marry them up somewhere down the line.
I like the idea of, for example, going to the vets and its a sim I made and clinic I setup treating my pet etc, seeing my other families about town and interacting with them.
Also trying to add more variety to my households instead of playing the same way each time for example paint and work early game, I want to try photography or busking straight away.
Lots of "save as" and see how full I can make my world :D
