It seems the general agreement is that people want more playable careers. Here are all the amounts of interest for every career (I grouped some together when they were similar)!

Second, with 12 mentions: ARCHITECT! People want this to be playable as well with options to actually design and build buildings/lots as part of the career. Maybe with special lot types you unlock to build as your career advances.
