Alright, it is done. Got 100 stickers and it only took me 106 hours of playing the game. While I was waiting for the last sticker, which was getting the 200 trading cards, I was trying to power through secret wands. Ended up getting Alice, Cinderella, Aladdin, Mickey, and Donald. Also bought the PoC content and did all of those missions. I can now put this game to rest, but it really spoke to me on some weird grinding level and all I could think about was getting those 100 stickers.
I came to this game after having played Animal Crossing every day for 1 year straight. I like that they're similar, but liked that I could technically "beat" this game. Think I will move onto Rune Factory 4.
