...lets hope this really is the final expansion.
While expansions are great/bad (depending on how you look at it) for those already sucked in, it certainly provides an obstacle for any newcomers to the game that this game has so many expansions. The obstacle is both monetary and trying to find copies on stuff which have a shelflife of maybe a year (and Mac games have longer shelflife than PC games). They should release a Sims megapack with everything.
