I have never participated in the GOTM. Until now, that is. I downloaded the .SAV yesterday and started to play. I'm looking forward to see if I can post a decent score. BTW - I decided to do the "Open" class, as I saw that they do not give out better scores when you do the "difficult" (can't recall the class-name). Anyway, being my first GOTM, I thought that I would opt for the "normal" class.
There was one thing I noticed (I don't think this is a "spoiler" point, hopefully not), but I popped a goody hut and got a settler. However, that settler was immediatley (automatically) converted to a city. I never play Expansionist, so maybe this is a "base" feature? Or is it something they did to the GOTM?
