Quoted from PinB:Could it have a multi-level playfield?
Judging from Steve Ritchie's past work, I'm guessing GOT will have some custom laser-etched armor for the LE (with slightly less cool custom armor for the Premium), as well as a few custom Steve Ritchie callouts thrown in (he managed to work his voiceovers into both AC/DC & Star Trek).
Steve could definitely voice "The Mountain" and his spoilerish later incarnation, as he's been played by 4 different actors so far and probably by another before it's all over. Also he's Shao Khan: Steve is more The Mountain than any of them.
