So as i understood you gain fame by being the best or strongest in certain parts in your era. Will silver and bronz prizes be added if the size of the game increases, or will there be more prizes to be gained. Also the naming largest mountain and river, if you play a larger game will you be able to name the largest river on your continent and largest mountain on your continent ? 

EDIT: Prize not Price 

Let me answer the three topics that have come up in this thread:

The Era Stars are not awarded for being the best in that aspect in the era, but for reaching specific threasholds (which scale up as the game progresses depending on your previous performance.) Each category offers up to three Stars, which you could regard as Bronze, Silver, and Gold awards for that category, but more than one empire could reach "Gold" status in a category.

Similarly, landmarks like named rivers, mountains, etc. depend on a minimum size, not specifically on being the longest/highest/whatever.

Regarding the maximum number of players, it will be between 8 and 10, but I don't know if we have settled the number yet.
