For those of you who remember, at the end of D1, the hero takes diablo's soulstone and is slowly corrupted, becoming the "Dark Wanderer" In the second game.
The new 'writers' at blizzard apparently didn't realize this, but the people who wrote Diablo two called him/her "Dark Wanderer" for obvious reasons. Being that the dark wanderer IS the hero from D1, the player is able to maintain a sense of immersion in their own story line. The hero is never named, because in your head, its name is whatever you gave it in D1. The D2 writing staff expertly handles this situation, tip-toeing around the dark wanderer, so much that you never really see his/her face until its half demon, so for all you know it could have been the female rogue from D1.
Two games worth of subtlety is then thrown out the window in D3 when the dark wanderer is given a name: Aiden. Oh. Ok. I though we kinda had something going there blizzard. In D2 you were super careful making sure the storyline stayed in tact, for my sake, and I loved you for it, now you threw all that work out the window. Gee, I wonder if this has anything to do with the vast majority of current writing/development staff having NOTHING TO DO with D2...but I digress. Lets continue, it gets MUCH WORSE.
I could bear with a name being given to the D1 hero. I suppose its more convenient. Then my jaw dropped when at the end of Act 3 when Adria says "when Leoric's Eldest son, Aidan..."
Wait...WHAT?!?!?!?! You're just gonna throw that in there like that? That doesn't make any sense at all. I played through all of D1, and listened to all the dialogue (it was awesome) and I'm PRETTY SURE somewhere along the way, someone would have said 'hey, I know you, you're Leoric's son' if the hero from D1 was leoric's son. BUT HE/SHE WAS NOT. You just pulled that out of your asses.
Its bad enough that D3 contains nothing really new creatively at all (Oh hey we get to kill the skeleton king again?...pretty sure I did that in D1...Oh hey its the butcher....and the lesser evils that were mentioned in D1 but couldnt fit into D2...) but to go and take a piss on the storyline of the previous games is unforgivable.
I'm not one to nitpick inconsistencies (ie: the templar says 'it is likely you saw me at an inn, I have traveled far' and also 'I've never been to the desert, I don't travel much'...meh) but something this major needs to be addressed. No blizzard, its not ok to come out with a new game that completely ignores previous games in the series.
