I think some TES references for an easter egg would be nice. Well since it's the same engine being used for Oblivion, "magic with guns" reference I think would be good for a Lul.

Sadly I don't know much about Fallout 1 or 2 or what ever other Fallout there is so I wouldn't know if there is a Fallout Easter egg or not. Another sad thing is most of the WWL stuff, I don't even get, and only say 1 that I knew of. The Indiana Jones reference, I didn't get or see anything else and thought it was a waste of a perk. I guess that is me to blame though. Would have been nice in game to see an explanation instead of reading it online.
