Hi, I want to get ready for Diablo3, but I didn't play Diablo/Diablo2 before, so...
I'm looking for Diablo and Diablo2 lore video compilation, similar to warcraft3 Lich King and Illidan lore videos below:
There really isn't a whole lot of fan made Lore videos out there, especially when it comes to Machinima.
Thankfully, or perhaps unfortunately, the lore behind the Diablo universe is pretty slim compared to Warcraft. I suggest reading up on The Sin War and just browse through the links in this case because, as far as I know, you'll be disappointed with your lack of results.
The videos do a good job with the information you are given, however Diablo 3 will reference a lot of information outside of what we encountered in the previous two titles with various sources.
Here's the original Diablo cinematics it's got a all the lore/story, fairly good for it's time too. This is the entire 27 minutes including the into and all act I to act V and the epilogue. Everything the game has to offer lore wise.
