Well, I think I'm going to give the Chieftain level another shot. I haven't find any good map yet, so there isn't much to talk about. As for the game spec: I'm thinking of having one big happy continent in C3C v1.15 with 8 other scientific civs; domination limit of at least 3800 or higher. I will play the Mayan, of course. My goal will be to give away all my techs at the end of each age in hope to gain all 9 free techs (3 for each new age) from the AIs.

Since the AIs are so weak anyway, I probably go to war with them really early and give them each a palace in the middle of iceland for them to retire - problem solved! They all can stay alive all the way until 2050 AD.
Since it's not really an optimal game, I'm just going to say that the final score will be around 1000 points less than the maximum potential score on this map.
