Let's see...

In Morrowind you have a slowly evolving story, in a world with better graphics than WoW even though the game is older, that eventually leads to you learning you're basically a god and have to kill two other gods because they've gone insane. At the end of the game, you radically alter about a third of the world map changing it forever.

In WoW, the story is basically "go kill the big evil guy", even if you're evil yourself because you summon demons, steal from people, or are an undead runesword wielding freak.

Oblivion's ending was amazingly dramatic, far more dramatic than anything I've ever seen in WoW. The dialog in Oblivion is worlds better than WoW. You have to convince the bastard prince to save the day with more nuanced story points than "go kill some dogs and bats for me... okay now I need to take revenge for my son.". That's Tirion Fordring's plot... real deep. If I see one more person in WoW change sides from good to evil or evil to good, I think I'm going to spit. Might be nice to have some more complicated plot points than that or maybe some plausible reasons or in depth character development. WoW has none of that...

And Simon, if you're going to disagree with me, make a point. Give me some detail about WoW that actually proves me wrong. Calling me whiner and saying other games are worse with no examples or points backing that up is fairly un-intelligent discourse.
