I don't think MWS lacks content. My only concern is that the theme itself is not appealing to me and I don't see how I can use all the wedding stuff frequently. I'm one of those simmers who don't play weddings, at least not in detail. My plan includes perhaps 90 seconds to find a white dress for the bride. But the world looks stunning, so I'll get this pack eventually despite of the wedding stuff. I don't see Tartosa as a worlds dedicated to weddings. I'm free to replace all builds, and to be honest there are not that many wedding related lots? Two? I don't mind a cake shop in town.
I wish there were more features to affect my everyday game, though. Collecting bottles is not what I call ground breaking. I'm good at making up new imaginary stuff, so I'll be happy with the new world and might add a few tourist friendly builds to serve my families living elsewhere.
