People are mad because the website can't handle the traffic. This is a game of 30k copies not millions. There is no reason the website shouldn't have been better prepared. This is a company that has made billions off of an online game. No excuse for the site to not be better prepared. They have even admitted it on there end too.
I dunno. Kickstarter has been doing big projects for years and their site still gets overwhelmed and locks up during the first minutes (or longer) of a big project. This definitely took way to long to straighten out, but the online shop that's peddling this game looks pretty small.
I didn't like loosing a few hours hoping to get through but what's done is done. In a week or two we will be having lots of fun ogling the minis and trying to destroy minion hordes. It could've gone much worse. Imagine if they had only ordered about 5k copies or decided to make it a limited edition game. They underestimated the hype. Definitely not the worse crime a game company could make.
