I have WA, Pets, Ambitions and High end loft, but I REALLY want generations. It just seems so cool, with the bunk beds and boarding schools and what
WA is cool, you can have alot of fun exploring the tombs and turning your sim into a mummy-plus you get new skills, photography and nectar making.
It has some nice household items and clothes, too, but I personally think I would prefur Generations, because I almost never make my sims go on holiday
But really it is a matter of personal opinion;but WA should be way down on price, because its been like two years since it came out. Hope this helps :-)
