Most of the groups, cept current one, I have played in have had female players. And as a rule all have been fairly fragrent bunch of people, with some idea how to talk to women/strangers.
Anyway on the subject of what worlds you would like to see:
I have always fancied a 17th century european style game. You got wars, civil wars, Religous hysteria and some very strange cults popping up in war torn areas. And pirates, i like pirates, me.
