Ora et Labora
In Saecula Saeculorum
..and yet Clash of Cultures got one first!
I believe that CoC really needs this expansion to achieve its potential. M&M does not imho. Any expansion to M&M will be great, but the game can really stand on its own, bringing player all the joy of being a merchant and, or, a pirat.
Do you remember the first negative reviews about CoC, that all armies were equal, that there was no elephant in the box, that the game lacked flavor and stuff like that. Even though I do not agree with any of that - were I the publisher or the autor - I would rush to make an expansion to shut every f... critic up, and thus claim all the glory I deserve for making such an awesome game.
