Xbox, because it was either that or Wii, but if it's ever released on PC, I'll definitely buy a copy of the game without anything and use my Xbox base and figures.
i have the 360 ps3 and wii u too i decided to get it for wii u for the reasons you listed also i love hearing sound from the gamepad and tv =D also with wii u being my newest console i have hardly played it since theres no games out apart from mario haha it will be great using the gamepad and walk away play ill play infinty on the toilet haha also the wii u can take a few terabytes of hard drive so i wont get stuck for toybox space
^I've said it before, and I'll say it again: I hope the mobile version is a city-builder. It's kind of like Rex being playable to Modeltrainman, only less.
