If its May/June'ish I should hopefully have time to play at least 1 game and I may as well play a megagame if it gets going!
The last one was awesome, even if I did not last 30 turns!
I believe many new/intermediate players lasted a long time in the game, either by allying with a large power or just got ignored. So if you have not got much MP experience do not be put off.
The most important thing to get right is the victory conditions, 60 players with 15 provinces per player is 900 provinces. So in the end game the few remaining empires will have 100 - 200 province empires, its not fun to run a empire that size for more than a dozen turns or so. Just takes too much real life time. Need a way too bring the game to a satisfactory conclusion.
