Missed out on a lot of polls, probably because I don't visit this site much (Might want to make a list of polls, so people can give you there two cents), anyways;
Should players be allowed to choose their gender? -- No, reason being you're pretty much a gang lord whoring out girls left and right, no? Typically, if say your gang betrays you, due to various reasons, there is more incentive to betraying a female then a male (Body). Also, there is pregnancy as well, if you'd allowing players to whore themselves -- in the old WM, girls had to take around a week off to give birth, and I'd think it's nearly the same here. -- Though I'm don't know too much about pregnancy, being a guy and all, I'm pretty sure it'll weaken you considerably, making it easier for rivals.
Gangs expanded -- I'd like to see them expanded, such as being able to add individuals to a gang, their own loyalty, and such -- they're rather static in the old one, where you could just fire them and send them to do your bidding, even if they end up nearly decimated, without any repercussions.
Marriage system -- I'm not too sure what you're going for here, so can't really say anything yet, but I can say that females are usually the jealous/using/betrayal types, especially depending on the society-- Reference being nearly all works of literal
Elements -- I'm not too sure what you'd be using this for, and how you'd implement it, so I can't say, but usually less is simpler and easier, but goes stale fast; more is complex and better, but annoying, since you'd to collect a whole bunch for all the different resist and weaknesses.
Anyways, I'd like to suggest, next time when you're adding a poll, give us an idea of what you're thinking, such as how it'd most like be implemented and such, kinda like an opening sales pitch; to get us thinking, and understand it concept a little better, of how we'd like it to be improved, etc, instead of just us voting on what we'd want to see.
