Do not get me wrong, I find this game to be pretty fun... For a facebook game, it is surprisingly good and the cooperative part is also quite good.
There is one problem however, and that is that if you're not in one of the two winning civs, you don't have a snowballs chance in hell to win. The reason for this is that the victory condition for each era is practically the same era, only with one more step... For example, in one era you can with if: You win a war; or get 4 wonders; or get 60 000 gold.
But for next era, the conditions are the same, except it is now 5 wonders and 80k gold. So the people that won last time with 4 wonders are almost impossible to catch up with by the other civ, except for the other civ that *almost* won the other round. All other civs might as well stop trying, or do a gargantuan effort. It would be more fair if your civ had to build 5 *new* wonders or you lost all your gold when winning a gold victory. Better yet would be if the victory conditions for each era were qualitatively different.
