Diablo 3

Since Diablo 3 is coming out on Tuesday, I've been doing some reading about the mechanics and watched some videos to learn more about the game.

This here is a great article by David Sirlin (sirlin.net / @sirlin) about the ability system of the game.
And here is a great post from the Blizzard Forums about character customization, with links to interesting Q&A videos with Blizzard's developers.

And, as a side-note, I found an unboxing-video of the collector's edition.
