How many turns are in the total game exactly? I know it goes in centuries until about 0 AD then 50s until 1000AD then 25s until ? I only have the demo, so if someone could create a little timeline or count for me that would rock!

I've only played the demo too, but I do know that the game is turn-capped, so that games will only take 2-4 hours tops.

No epically-long games to be had here. ;)

EDIT: Just found it. 2100 A.D. as reported here: http://forums.civfanatics.com/showthread.php?t=279776

I know it ends at 2100 AD but what is the space in years between turns at different times and what total amounts -_-

I suppose in the space stages, the years go by with only 2, this means you'll have to wait for about 6-7 turns before your speceship arrives. (It takes 12-14 years)
