I tried to download the Grand Campaign and 1492 scenario here on BGG to start reading them, however both downloads failed. I had no problem downloading Extension No.1 & No.2 from the files by the same BGG user however It failed me on the other two.
I also tried to look at the contents of the game but It looks like it does not cover the Grand Campaign or 1492.
Is this correct ? The base game does not cover the above two ?
