The only real point of criticism for me is the disappointing cave discovering experience. It's just not satisfying to have that be a rabbit hole. Doesn't add anything, except that you can apparently find collectibles. But it's so frustrating to read about how they discovered a lagoon or whatever and not be able to see it and explore there :( But for the rest I really like it. Yes, you can't take much of the pack into other worlds, but it's more like a liveable vacation pack anyway. However, if I'm really honest, I also don't really understand what the considerations are for classifying something as game pack or expansion pack. Maybe it's more of a game pack than an expansion pack, that could very well be true, but I do think it's worth the money.
