For our wonderful GOTM administrators:
The intro page for each game of the month gives good instructions on what we need to install. At the bottom it says:
"If you have not previously recently played and completed a GOTM game, then download the "Gotm21 Total Install" first and then add the Add-On packs for Gotm22, Gotm23, Gotm24 and then add on the Gotm25 game pack that matches your software. You can download the Game Packs from the game pages in the menu at the left hand side of this page. Please pay close attention to matching the game pack versions to the software version that you are playing as this will eliminate 95% of all the errors that have been observed in the past games."
However, I once installed to the wrong folder (the PTW sub folder instead of the main Civilization folder). I also noticed that in the GOTM FAQ this is a recurring problem. Perhaps there should be an added line that says something like "Please be sure to install the files to your Civilization folder and not to a PTW subfolder if it is present."
These are not the exact names for the folders as I don't have Civ installed on this computer.
On the GOTM 31 feature page there is also a teeny tiny error. It says "Predator class game details for GOTM 30" rather than GOTM 31.
