Preloading it now.
In the days before Steam, a launch day like this would mean me frantically calling the stores nearest me to find one that had a copy I could pick up.
These days though, I just download everything.
Part of me misses the trip to the store. Reading the manual I know would be useless while the game installs, and actually having the physical discs. But Steam is just so easy.
And to think, several years ago all I knew about Steam was that it was "Some crap that Half-Life installed".
I think from this point on, MMO expansions are the only games I'm going to physically buy, and only for the entertainment of seeing all the cave dwellers as they make their annual trip out into the real world. Also so that I can try to find reasons to convince myself that I'm not as much of a nerd as any of them... but inevitabely get drawn into talking to strangers about Paladin class mechanics..
