There is really NOTHING in this pack if you don't want to play with Star Wars. The Build & Buy, decor and clothes all look like they are meant for Star Wars and nothing else. It all looks completely out of place in the other worlds.
Also, there are NO gameplay mechanics that seem like they'll be useful in other worlds, unless you want to see sims have light saber fights in Willow Creek :D
In other words, unless you're really obsessed with Star Wars, DON'T BUY THIS PACK
"Maybe now your daughter/son can be a Star Wars fan and her/his room can be decorated with SW content." -but is it really worth spending $40 to decorate someone's bedroom??
