There's really only one important thing to take away from the new trailer for The Sims 3Ambitions expansion. The expansion allows players to extend the lives of their sims, endowing them with many different career options, including inventor, fireman or a detective. None of that is important, though. What is important, is that the expansion allows you to be a Ghostbuster. Legal reasons probably prevent it from being called ghost busting, of course. Atari and EA's lawyers wouldn't want anyone crossing the memes, after all.
Check out the ghost busting catching action -- along with the other professions -- in the trailer above.
