UK multiformat gaming magazine GamesTM is one of my favourite reads, and always has great Retro articles. They are also great fans of the LucasArts adventures and often have some sort of feature on them.
Like Issue 98, which should hopefully be still in the shops, which has a big feature on The Curse of Monkey Island to rival even their great Fate of Atlantis article (anyone got a link for that?). Being out of the UK right now I can't read it, but I'm told it's very in-depth, with lots of photos and a huge interview with project leader and friend of Mojo Larry Ahern.
Go buy! And report back to us with your findings!
