Nah, its just that if you got everything, you got evertything.
Only thing that's left is the avatars and you modify it until you finally find the dreamy combination, you don't have to spend anything else except for replay slots and new ex/set/event cards that come out.
Partners would be nice too, but there's still same group of partners for like forever and I only like magic doll out of current selections
Its just that, partners is tad expensive for limited use xD meh
Just goof off and have fun ropey.
Oh and don't buy the potions, they're just gran sinks. not worth it lol only good thing about them is the flavor text which i like reading from time to time.
