Would be fun to watch the corrupted blood incident play out if this was the case.

Funny, I was doing exactly that to help someone create an emulator :D More specifically, recording all packets between the server and the client.

Tangentially related, but this recent article is one of my favorites about WoW and nostalgia: http://kotaku.com/the-people-who-still-play-world-of-warcraf...

Giving up the girl to kill the dragon, don't think i'll ever have that level of dedication to a game. But perhaps it was more the community thing than the game thing. I keep having the impression that what keeps many playing WoW is that it is pretty much a oversized chat room for them. That is where the people they know "hang" so that is where people need to get hold of them, and so it becomes self-reinforcing.

Would he interesting to see what I was doing when leeroy jenkins happened.

That is an amazing idea, I wonder if Blizzard stores such data.

Incredibly unlikely. At the current moment even 3 hours of movement/combat between 20 players results in log files of ~0.5 gb

Now there is a decent amount of it that also tracks data generated by the actions (and not actions themselves), however without it, due to RNG you will get different results (even with the same actions)

Unless blizzard decided to implement a truly monumental storage facility, i doubt they would do it (for all actions)

They do however store some of the actions, mainly with the intend of recovering items/etc.

Well inventory changes and such has to be stored somewhere to provide persistence. So rolling back that should be easy enough given proper backups.
