I'm not feeling all that creative either and I tend to go really deviant when that happens, but I just started a game where I'm focusing on just the premades. I want to see if I can complete main aspirations on as many of them as I can (playing in rotation) as I can before some other idea comes to me. I don't usually focus on premades as their own character they normally just revolve around my sim or family so I'm kind of excited at the moment to try to play this way. I want to play them as I think they are intended to be played if that makes sense.
I've been in the Goth household and Johnny Zests so far. I was kind of amazed that the first thing Mortimer did was go read a book (he's on an aspiration that needs that) and Cassandra went to play the violin... and that's the aspiration she's on. Alexander went to read also. Bella stood outside and waited for me to make her do something.. lol.
It's fun to step outside how you normally play sometimes I guess. I'm having fun with it so far although not sure how long playing this way will last for me.
