First post here, as I was following the rumours and speculation from Friday and thought I'd sign up to chip in.
I have an Attack from Mars at present and I'm looking for a change. Game of Thrones is a great theme for me and I have my name pencilled in against an LE. First impressions of the artwork is very underwhelming. Like most others I'd prefer it to be dark, but this to be designed to attract people in arcades etc (more than just fans of the TV series and books).
Playfield looks very interesting in terms of shots and toys. I'm a little disappointed that the artwork is generic but it'd be impossible to try and fit every character from the show on there. Someone will always complain that one character or another has been omitted. Interestingly, I thought the same thing about the Star Trek playfield when I saw it, and that game plays well. Stern have said you can choose you house. With seven houses, how could you incorporate enough characters from each one on there (as well as dragons, white walkers, the Wall etc) without it looking very, very busy?
Finally (since others have mentioned it), I've had the Alien sneak peak from Heighway at the UK Pinball Party and, if it ends up looking anything like their plans, it could be very interesting. Continued delays and a relatively new pinball house put me off though.
