I've seen this game very recently and it looks amazing. Scribblenauts is basically a game where users can write in any word in the dictionary and it will go on game, you can interact with these items greatly to do all sorts of things.
For one example : Theres a star that you need to get stuck in a tree, in this case you can type unicycle and then panda, get the panda to ride the unicycle,get another panda to sit on top of that panda and then type stick so you can get on top and knock the star out of the tree.
Even the stuff yu wouldn't expect is in there like the Flux capacitor off Back to the future. Theres the liger which is Napoleon Dynamites mix of a lion and tiger and loads of other internet easter eggs like Lolcats and even easter eggs themselves.
This game looks fantastic to me and I'm certainly going to be picking it up when it comes out in September (Europe). It has anythign you could imagine and the only downside is that it seems like it may be too easy. Theres 220 levels each trying to get you to get the objective of the level done for stars. And the best part is theres no spam on the game.
Will you be getting this on release day? If so, what are you going to try out?
