FFS... First Rayman Legends and now this!. I'm thinking of canceling my pre order and will wait until next year. Thanks a lot Nintendo for putting a downer on my day.

i only see: "for the Wii U™ system, Nintendo 3DS™ hand-held system and PC this holiday season."

too bad. this will be my first scribblenauts game. hm maybe i will get superscribblenauts then

I doubt Nintendo had anything to do with this unless they're publishing it in Europe

Don't know why it's been delayed till next year,as the previous 2 Scribblenauts games launch around the same time as the US.

I was originally a little disappointed when I heard this because I've preordered the game and plan to get it with my Wii U at launch... but then I heard that apparently it's only Europe and not Australia (which is pretty weird) so I'm happy.
If there's anyone in Europe that really wants the game this year, then just buy a copy online from Australia.
I'm assuming it'll be on the eShop too, so if you're happy to go down that route then it's also possible to just change your region to Australia and download it (I'm assuming the Wii U eShop works similar to the 3DS in that regard).
Could be a little more expensive, but it beats waiting till next year.
Normally it's us that have to buy from there.

I don't see any reason for this to be delayed for Europe. I got it along with my Wii U and it works fine, so it's not a problem with the physical game.

I was really interested in this, but I heard the puzzles are really lineair and impossible to solve creatively. How are your experiences @Popo_man?

@Sjoerd

The game is a little on the easy side, but it is really fun and pretty long compared to the previous games. There are still some nintendo characters that haven't been announced by 5th cell, but are in the game. It is an overall very fun experience and I recommend it to anyone who enjoys being creative.
