Here are some G&K suggestions:
Attila, huge, domination, pangea, quick, warlord
A nice massive race to have fun using the ram. The previous Attilla one was quite popular (counting multiple subs there was 33 entires) and this is that one but ramped up.
Attilla, diplomatic, quick, tiny islands, standard, highest score, emperor
Personally I like the "use a leader in a different way" ones, so attila on islands and having to play more peaceful than usual meets that.
Austria, science, standard, tilted axis, standard, highest score, king
We haven't done a tilted axis (least that I know of) and using Austria to buy CS's for extra science sounded fun.
Ethopia, OCC, domination, king, continents, standard; opps are: Alex, Attila, Bismark, Monte, Catherine, Dido, Harold
This is to really use Ethopia's ability and to make all the war more interesting the opps are warmongers or very strong UU's.
Spain, pangea, domination, prince, standard, large
I wanted one with spain, but all the victories except domination want a reroll until GBR. This one could be interesting because the UA will help but I don't think it will be a reroll fest.
Any leader, shuffle, science, emperor, standard, standard; opps must include: spain, korea, babylon
Shuffle plus shuffle for fun. I included the 3 opps to force people to not just use those 3.
Boudicca, arborea, chieftan, large, domination, epic
Was thinking of a holy warriors fight. Could go for really early religion and build lots of faith from the forests to buy a lot with the holy warriors belief.
Dido, diplomatic, tiny islands, standard, standard, emperor
This is to split the benefit of Dido, harbors would be helpful, the UU's less so.
William, lakes, diplomatic, small, quick, prince highest score
Poulders can make for gigantic cities which is something I enjoy seeing.
Harold, frontier, large, standard, king, domination; opps must include: alex, bismark, washington, monte, catherine, dido, wu, caesar, attila
This is a all out war while exploring the "frontier". This is one I would want always war on for.
My suggestions were a combination of fun sounding things with the leaders, filling tables, and suggesting some high score games (I know they aren't exceedingly popular, but I still enjoy them
)
