I folded and I'm all in on getting this game ASAP. I was just going to get the The Art Of Alien: Isolation book from
www.bookworld.com.au (best price on the net if you live in AUS) as the book depository prices are moving inline with the increase with postage in the UK.
Good place to find games at the best price
http://comparegames.com.au, just change the search to your preferred country.
If this game is a bum deal in the end I don't think there will every be another Alien game made.
