Thanks for keeping this going. The first thoughts that come to mind in terms of feedback are that I really don't like what I consisder the more 'gimmicky' game settings, such as One City Challenge and No City Razing, as they restrict play in a way that just makes the game less fun. On the other hand settings like Raging Barbarians and No Goody Huts can be useful on the higher difficulties. More variety in maps wouldn't be a bad idea, although less use of the types that the AI struggles with (basically all island style maps) is definitely advisable.
Other than that, I remember particularly enjoying one game in which the player was required to complete particular Social Policy trees (I think it was an Inca game). Also, playing as a wider variety of civs would be very much appreciated; if you look back through the game history you do see the same ones again and again, whereas I feel like I've never played as civs like Portugal or Brazil.
