The thing is, I like the concept....I just hope it's executed properly. I would have been excited if you could use the stickers in any way you want - i.e. stick it on menus screens, the character selection screen, characters, levels, anything. But sticking them on a piece of paper just seems kind of...lame. The update did say that you can stick them on "things", but I'm not going to read too far into that. I'm looking forward to more info.
Even so, Sakurai and unnamed developer are really putting A LOT of content into the game. You can tell how really determined they are to make a SSS game, and they just keep piling on the features.
It brings a tear to my eye, tbqh. I can't believe all these stupid drama queens putting this update on the same level as "banana peel" and "you must recover". >_>
