Reading the numbers you guys are throwing around in this thread is just jaw-dropping. You mention 999 gems like it is an everyday occurence! Crazy
In response to an earlier comment - I've found that a good victory condition is around 40% (territory or VP). And the number goes down the larger the game gets so you might go to 30 or 35%. I know that, on the face of it, that number sounds too low... but it really does work out pretty well.
