I finished D3 earlier today w/ my Solo Character (Witchdoctor) on Normal.
Damn, what an awesome game!
It's awesome, even despite some of my minor complaints (no way to sink points literally into your character build like in the older Diablo games so players can have some different builds of the same exact class; graphics aren't anything spectacular technically...especially when zoomed-in); AND of course my MAJOR complaint (the always online DRM - especially in a game that is VERY SP-friendly and is even more SP-friendly than ever before).
EDIT:
I really LOVE the way they took the mechanic of giving the player tons of info and backstory, as they are playing.
The way the Lore works, it reminds me of the System Shock 2 and BioShock mechanic of when you find a new Log - you can play it NOW or listen to it in your Logbook. When you pick up some sort of Lore in the gameworld; encounter certain people; encounter certain events; or say kill a monster for the 1st time -- this Lore is all for you to read & listen to all voice-acted right then and there w/ the click of a button. Miss one by accident b/c you didn't hit the Lore button in time or do you just want to listen to it later? No problem! All of this Lore, it's stored in your Logbook - so if you want to listen to it later, go right ahead and open your Logbook up and read and play the audio at your own discretion! In an ARPG, this stuff never seems to get in your way of your actual gameplay. This stuff is perfect to listen to & read this stuff when you're taking a break from the breakneck face of action - like say when you're back In Town doing much more relaxing things than slaughtering monsters.
All the NPC's even have their own back-story and you can chat them up for more info, as well. Even your class character, he has his own story - you can hear it tossed in here and there, when he talks to other Followers or NPC's; or even in the Main Quest stuff sometimes. I love the way Blizzard didn't pepper too much at once & made most of this stuff optional to get involved with - as you can pretty much ignore most of this stuff, if you want - and just want to go ahead and slaughter things. The game doesn't seem to have many in-game cut-scenes - and even when it does, they don't seem to be that long, either. I really like seeing this stuff in an ARPG - and they seem to have taken this stuff to the next level & set a new standard in the ARPG genre.
