OP checking back in here just to update anyone curious I was on within 2 hours of getting home from midnight release at GameStop (was out of there and home by 12:30 or so, I had it already installed from digital purchase on desktop and laptop both but I had bought a hard copy for the booklet, cd, box and gave the serial key for that one to my gf) so I was on by like 2:30am and played to level 10 on my demon hunter until about 5:30am, I was satisfied, it went pretty smoothly for those 3 hours.
I'll play more tonight but probably after some sleep.
Oh and btw, I'm blessed to be the sort of person who does not even begin to give a shadow of a shit about ladders, or staying ahead of other people... I just want to experience the story, and occasionally play through with gf or a couple close friends I've gamed with since 1994 when we were all 14. We all played Diablo 1 together, less so Diablo 2 but somewhat... so I like to have the option to run some dungeons with them but for now I'm focused on just seeing the story for the first time more.
I will bitch about the online requirement for single player until the end of time, I've known about it for months, doesn't matter... it will never stop being a bad decision worth bitching about.
Not only for the submarine reason but also due to the fact that my net connection is somewhat unstable like the llama guy above me, it's not DSL but the cable cuts out on a fairly regular basis...
