Some thoughts about Space Hulk:
1. Yes the miniatures are good. But GW has been doing a higher proportion of exquisite minis for a while. On the flip side you'll have to convert to get away from BA and they won't fit a standard carry case - incorporation into standard armies would be hard(er).
2. Yes Space Hulk the original was tops with the 2 expansions. I still play 1st Ed. Yes all the game and both expansions goes for £150 on Ebay. But can GW be trusted not to dumb the rules down because look what happened to 2nd Ed? Where is it now?
3. It might be a limited edition. It might be an old favourite. But this rehash is far from the 'never been done before'. With the ability to have done a plastic tile board using the cities of death tech, that alone would have been revolutionary for GW.
Quite frankly whilst it looks good I don't think this matches the hype and I have no idea what is making grown men run around creaming themselves. Next you'll be wanting mass hysteria if a princess dies in a car crash.
Space Hulk is about game play. As stated you can get brilliant minis already. So not sure why a true fan would not just have ebayed 1st edition - the only thing about this set is if you are a collector and want all 3 eds or a complete game to sit on a dusty shelf.
I for one don't think the hype has been lived up to and as, after the revolution, advertising executives are amongst the first to go up against the wall, I feel just slightly disappointed that it is ops normal for GW, as opposed to something truly earth shattering.
