Blizzard could've made it easier to replay if you didn't have to go through the same dialog (story) again and again.
I got half way through Nightmare and was like "I am not wadding through this crap dialog again". And put the game down.
The "story" was lackluster at best. Easy to predict. And absolutely no surprises. And to make me run though it again, at each difficulty level is just mean.
Additionally, the boss mechanics were extremely disappointing for normal and nightmare, so there's no real triumph the first two times you play through the story. For most of the bosses, you have to _try_ to die.
I'd love to play hardcore, but the friends I play with aren't on board. I love the idea of it (and I've been watching some Hardcore-Inferno players on TwitchTV)
You can hit space bar or escape to flip through the quest dialog more quickly. There's only a few places where you also need to wait for an NPC to do something, but they're far enough between that it's not a huge issue.
