[1.2.248] Mushroom Castle

According to Wikipedia Nexon is 2nd party to Nintendo, and besides I think this would fall under the category of parody anyway. It's kind of like having "Charles, prince of Whales" on the nautilus. Sort of homage and parody taken past the logical extreme.

also I don't get why you people are thinking this is wedding related? they already have Amoria in KMS, and beyond that Amoria's integrated into Magatia's quests now so it's basically tied in forever.

Well, I was referring to the Scouter and that type of thing.

I'm guessing they're second party due to the Maplestory DS game...

It's not exactly clear based on what Wikipedia says here, but it seems like NoK had a big thing going with it for a bit.
