New active career (acting)
New world (despite the number of lots it seems to be pretty big)
Two new game mechanics: Fame and Reputation
A lot of new objects: high end furniture for the rich folks and MidCentury Modern type furniture for everyone else
Fame doesn't just apply to Sims in Actor career; any Sim can become famous through their careers or other activities if they so choose.
When you look at the pack as a whole, it compares well to packs like Get Together (which didn't have a new career but added the club mechanic plus the dancing and DJ skills), City Living (which added three semi-active careers plus festivals and karaoke), and even Seasons (which added weather plus the semi-active Gardener career). A game pack would have probably focused solely on acting and ignored all the other careers when setting up the Fame system.
