(Didn't vote again, btw).
Just want to point out (espacially to the scenario designers, and to everyone who wants to know what Conquest is worth to be played next) that the rating system is misleading in what conquests are actually good. For example, if there would be one Conquest EVERYONE would consider second-best, it would end up dead last in the ranking, despite being highly popular. That said, here's my complete list.
A:
1) Middle Ages
2) FoR
3) Mesopotamia - the 3 scenarios I really liked
B:
4) RoR - great Scenario, but nothing that wasn't already availble in ptw - see the TAM Mod
5) Napoleonic - Great for some nations (especially Russia), boring for others (Ottomans)
6) WW2 - good Conquest, just suffering from the known AI incompetence in modern warfare (Artillery, Air Raids, Naval combat).

for the designer, guess there was no way to do a better job. Now, if I would play MP...
C:
7) Sengoku - Yamabushis, HN bug. Guess it would be a great, epic conquest, but those 2 seemingly minor problems totally killed the fun for me. Will mod it and retry.
8) AoD - Well, a Conquest you win at first try without looking at the techtree etc before in less than 4h at Emperor level isn't exactly challenging - the AI simply doesn't do well with the shipments. Well, I could try it with one of the American Civs, but...
E:
9) Mesoamerica. I'm really a history freak, but throughout the entire history of mankind, no topic is less appealing to me than native American cultures. Just a question of personnel preferences. And, this Conquest has serious level balance problems - as long as you have any chance to build a few Wonders in your Capitol (in other words, Demigod), victory is sure. No wonders - no chance. And the Civs simply start too far away to make any other victory condition viable, especially since conquest/ unit kill gives no VPs (IMHO the biggest design flaw).
My prefered era in the 'epic' game? Cav/ Rifleman/ Cannon age.
