Early copies risk spoilers, leaks, livestreams, having the whole thing uploaded to YouTube, etc - so the timing of distribution of physical backer copies has to be very precise on Fangamer's part to ensure nobody gets it too early.Is there any reason why YSNet couldn't ship the game and the bonus stuff so that it arrives on or as near as dammit to the release date? I've bought 3 copies ($300 edition for myself and two digital copies for friends and family) and I really don't want to purchase another copy just to play it on release day. I want to support the series as much as possible, but I think $360 is pretty fair...
However once it's in the postal system... there's not a lot they can do past that point. They may send copies out with the best intentions of them being received for launch day, but they have no control over what happens afterwards.
@Drakub already made the point above that even Amazon has trouble getting games into people's hands on day one, with their regionalised distribution centres and strong infrastructure. It's never foolproof, no matter how big or organised you are.
If you want to absolutely guarantee you get your copy day one, you either pick one up yourself or buy digitally.
