But lawks a lummy, Maxis have only gone and released that part for free! The 'Create A Sim' character creator has been yanked out of the full game to make a demo (or we can treat it as simply a cool toy for everyone to play with).
No matter what's removed or added or changed or bro-ised with The Sims 4, we can be fairly certain it'll allow one thing: making goofy-looking folks.
