It is interesting how viable non-standard games are.
From reading forum posts, I understand the original concept of the game was 80 planets, capturing about 15 worlds and destroying both AI homeworlds about the 12 hour mark.
We have people who play it that way, but we also have people who play 10 planet really quick games all the way up to 120 planet marathons where they capture every world.
A testament to the game I think that it does support all these different games reasonably well.
