I can't wait for this game. LEGO has an excellent reputation of making games with tons of characters from the story. With the only exception being LEGO DC Super Heroes, which only had about thirty, all LEGO games have about 90 or more characters. This game is confirmed to have more than 100. This means possible characters like Ant-Man, Cyclops, Thanos... the possibilities!
For instance, Ant Man could turn from a small-sized character, which can fit into holes, into a large-sized character which could throw cars and stuff.
