I tested marathon because i wanted a game with marathon, that's all

I'm not testing the RR, just the industrial start ^^
and the second tech was reached after 150 turns not 100. (I ended the game turn 250, but the map was mostly water with few islands and IA was bad at handeling that)
but if you count that marathon is twice faster that epic and 3 time that normal, that mean that the 2 techs will be founded after 75 turns in epic and 50 in normal. (I may be wrong, but that's the way i understood it)
That's the only thing i wanted to figure out.
for leader:
we will build settler. I mean at least 3-5 just for strategic reasons.
We will be very happy if they are half costed. To give you an idea, their cost is similar to oxford university

other interting traits are Philosophical (earlier GP mean faster start), agressive, organize (it is always good) and expensive (mostly for the +2 health bonus - a major concern when we strat building factories building)
but choosing the traits would make the game too easy, i prefer randomness now.
