I'm not sure why people are having such a hard time with this. You are not being forced to buy into the Fang Club to purchase. A perk of the Fang Club is the ability to order 2 weeks before it is officially for sale to the public. You are not being forced to buy without seeing gameplay footage as the game is not yet available for sale to the public. I am fairly confident (and if I'm wrong, I'm wrong) that there will be gameplay footage available by the official public on sale date.
Now realistically, yes, Spooky has grown popular enough that there is a very real chance that they will sell out to the Fang Club members ahead of the public sale date. That is a risk you need to decide whether or not to take. That really isn't Spooky's fault...it's "ours". This was a nice thing Spooky decided to do for our benefit to give us enthusiasts a better shot at getting one as opposed to those nasty muggles. Those that are scrambling in just the last couple days to get a membership really aren't using the perk as intended. You shouldn't be trying to buy yourself a shot...you should be a fan of the company enjoying an extra perk. They probably should have shut down membership purchases about a month ago to avoid this, but imagine the complaining if they would have done that!
Spooky, and really all of the manufacturers, are just always in a no-win situation, aren't they. There is just no making everyone happy.
Best of luck to everyone buying today (for the right reasons, F you to the scalpers hoping for a quick flip).
