Honestly this is probably the last time I get a game from Amazon. I love Amazon, but delivery services are freaking the bane of my existence and I won't rely on them for release day deliveries anymore. I'll just pick them up on the way home from work.
I have always been surprised that actually this many people order from Amazon and other online stores, I would hate ordering a game this highly anticipated online and not knowing whether or not I would get it right on release day, or the day after, or the day after that, etc. I suppose its mainly for convenience, but I don't personally mind taking only a 10 minute trip to the store to buy a game I'm looking forward to.
