I got a reply for my support ticket asking if I could just get a refund for the digital version of the game once my CE came. The answer is yes....but I'll lose all my characters. The part on the forums about being able to receive an unused digital key back was true at the very least.
I'm not sure how it would hurt them to just issue a refund, but it's the answer I was expecting. I'll play whenever UPS decides that I can, I suppose.
That isn't the case for video games in general.
There are media tie-ins to some games, like the aforementioned Angiris Council animated short. I digress though; I've received an answer to my question of if there are any other videos I can watch without being spoiled (by my definition, which I'll admit is extreme).
Honestly, LordCanti, if you're on media blackout, my best advice is to get off the internet. Someone will spoil you if you don't just get off and do something else. The cinematics and a couple twists in the story have already been datamined and posted on Diablo fan sites. It's inevitable.
This is the only Diablo related thing I read. I won't go to wikis, I won't watch Youtube videos (except ones posted here, with the comments disabled), I won't go to the blizzard forums, etc. As long as people here don't lose their shit and start posting unmarked spoilers, I should be good.
