Hey Arthur! I love Lego Dimensions, and I love the new additions like Sonic, Adventure Time, Gremlins, and Beetlejuice. Here are some questions.
As much as I loved the addition of Adventure Time and the Powderpuff Girls, have you ever considered adding some other Cartoon Network or Hanna-Barbera worlds for Year 3 or 4 like Steven Universe, Ben 10, Dexter's Laboratory, Courage the Cowardly Dog, Billy & Mandy, KND, Samurai Jack, The Flintstones, and Jonny Quest?
Do you think it's possible to add Spongebob and Ninja Turtles in the game cause I'm not sure if it's possible since Mega Blocks has been making sets for them, even though Lego used to. In case it's unlikely, then Avatar: The Last Airbender and or Jimmy Neutron might be Plan B.
Other clever additions in my opinion should include Shrek, Spaceballs, Animaniacs, Willy Wonka, Jaws, Looney Tunes, Peanuts, Mars Attacks/Pee Wee's Big Adventure, Who Framed Roger Rabbit, Despicable Me, The Mask, The Iron Giant, and Shantae.
