From what I can tell, all the major complaints have been from the VIP backers, who paid hundreds of dollars and didn't get half of what was stated they would get. So I could see, were I in that situation and payed $200+ for features and benefits which weren't "delivered", why I would be upset about that; no matter how good of a time I had.

To put it in pinball-ese: if you paid the full price for a ST premium, but instead recieved a ST pro, wouldn't you be upset? The pro is still a great game as you'll enjoy it a lot, but paying the premium price and expecting the premium for something that others have gotten at a fraction of that cost would still rub you the wrong way.

I'm glad great times were had though! It would have been a daunting task for anyone to make run smoothly!
