A little while ago, I was in the Metro Kingdom and I bought the "Shopping In New Donk City" power moon necessary for 100% completion. I then saw that I had the option to buy 10 more moons and assumed that this was also necessary to get all the moons, so I bought them as well without realising that those were optional for skipping the harder moons. I can't remember if I did it again before I realised that something was off - depends how stupid I was feeling that day, I guess.

What I wanted to ask is, will I still be able to collect the rest of the moons in the game legitimately, or will the game give me whatever ending there is for getting all the moons while there are still moons to be collected?

Cheers!
