There's nothing wrong with that and a drow city is extremely complex and hard to manage, YOu have to absolutely know every little nuance going on and have to keep track of multiple plots all going on at once if you want it to feel authentic.
You're right, but there's not really room for more guys in a one-man-show plot like his. As for the other complaint, it's all a matter of being obsessive, a trait I fortunately have in abundance

@Myrleena: Well, part of it is that I want to know what other players want. But I'm thinking something along the lines of House politics; for the sake of simplicity, have only a few Houses of incredible power (Like Erelei-Cinlu) rather than dozens of weaker ones with a few top-tier houses (like Menzoberranzan). A fun little twist would be to have all the Houses be of roughly equal strength, but in different areas (one having the most priestesses, another the best soldiers/Weapons Master, another a penchant for arcane magic, etc).
There would be the facts of drow life to play around; the submissive position drow society forces on males, and their living in it or fighting against it; the Machiavellian nature of drow politics and hierarchy, and players moving up and down within it; the state of war with (most likely) every nearby settlement in the Underdark and above.
I think the most important thing for me is my hatred of the 'noble rebel against the debauched society'. Drizzt was awesome because he was unique; Xeroxing him over and over again just results in these twisted little things that give the whole concept of drow a bad name. I *don't* want a player-set of Drizzts; I want wicked, sensuous, diabolical dark elves that are so much fun because they are so EVIL.
@Kol: My preference for these sorts of things is usually free-form but D&D-based; no, you don't need to roll up a 3.5 character, but some understanding of the mechanics of magic, for example, is good. As well, a vague kind of idea of power level is nice, establishing which characters are the powerhouses in the city and why, and which ones are the above-average but not epic.
As for GM, I usually try to pseudo-GM any games I try to set up, but I don't usually make an actual job out of it. I'd settle disputes, set the guidelines and enforce them, and provide new plot direction when things get old. But this isn't meant to be the War of the Spider Queen, with an overarching mission and such. This is more meant as a sexy drow soap opera sort of thing.
@Black: I'm not sure what you mean by the question, honestly. If it's what I think it is, it'd probably move at a day-by-day kind of pace. Like I said, more of a day-in-the-life kind of game than Epic Quest for the MacGuffin.
