I like to think with Alduin that he only just got out the dimensional rift so is still a bit out of it, your dragonborn status is still dormant at this point so he can't exactly pinpoint which human is the dragonborn ergo decides fry them all let Akatosh sort it out. He just had a bit of bad timing being a bit too early.Sniper Team 4 said:3) Ah, Alduin. The fight's even worse if, like me, you've done all the other side quests before that point, because then you just stomp him. And can someone explain to me why he attacked the little outpost you were at at that exact moment? If he had waited just a few more seconds, he would have won. To this day, I have not come across a good reason for why he chose that point in time to make his return.
OT: Yeah I pretty much agree with the list except Wesker because RE is cheese.
