If you've somehow missed news of the game, Lego Dimensions will bring together a host of Lego themes, both original Lego creations and numerous licensed properties (some making their Lego debut), in a single video game, allowing characters and vehicles from different Lego worlds to interact.
The core of the game is the toy pad, which allows different characters and vehicles into the game. The starter pack (available on Playstation 3, Playstation 4, X-Box 360, X-Box One, and WiiU) includes the toy pad, plus Batman (DC Comics), Gandalf (Lord of the Rings), and Wyldstyle (The Lego Movie), as well as the batmobile.
Additional characters, vehicles, gadgets, and game content will then be available as separate expansions, in the form of level packs, which include new levels in the game, plus a new character and vehicle/gadget. Other expansions will just add extra characters and vehicles/gadgets; either team packs, which contain two characters and two vehicles/gadgets, or fun packs, which add one extra character and vehicle/gadget.
To kick off promotion of the game Lego released a couple of rather cinematic trailers, focusing on the drama and scope of the licenses involved (continue after the jump to watch them all).
