There‘s been around 5 really good ones since launch, the rest are mostly awful. The good ones have been great and become my defaults, but they're usually just hideously coloured junk.
I’m undecided on whether I prefer a sparser seasonal store or not. On the plus side, I like affording everything after a single playthrough without having to go back and grind if I want to unlock everything. On the other side though, it’s obviously disappointing if there’s very little to spend your hard earned coins on, especially if what‘s there isn‘t any good in the first place.
