Ok, this is the second and final thread I'm opening about the subject; I'm doing this as I thought not many people would find out about it unless they read a clear topic title; so here goes.
As requested, I've translated all 10 scenarios from the Edge Entertainment spanish league into english, and uploaded them in EON format to boardgamegeek. You can find the link in the Arkham Horror page, but here's the direct link to the first scenario: www.boardgamegeek.com/filepage/48892
I've also added the links to the other scenarios in the file description of each one, but unfortunately for some reason I was forced to include the complete text link next to (instead of "into") the scenario name, which doesn't look too good, but... that's the way it goes.
Hope you enjoy them. I'm sure there's bound to be lots of questions about the rules of the scenarios, but... don't ask me, I'm only the translator!
