Is "My Wedding Stories" worth buying?

Well, even if it is mostly fixed, the pack doesn't add a lot of gameplay, even for the weddings themselves. Based on gameplay alone I wouldn't get it myself.

However the true selling point for the pack is the world, cause that's where it looks like the team put most of their resources into, so if you feel like the world of Tartosa is worth the price tag of the pack, go for it.
