In short this is usually completly up to the host, of course it's up to the players if the want in on those terms =). Those mp games I have played the host have usually picked a map with around 15-25 provinces per player, and more than often the site frequency is abit higher than normal (around 50%). It's good in my opinion to use victory points so the game can be decided in a reasonable amount of time. All other settings are usually pretty standard.

But of course this is completly up to you, just pick some settings you would enjoy to play and im sure others will sign up.
