You're good up to here. This one, however, gets real sticky in that you're opening the door to letting players tell other players what they're allowed to play. And that never ends well.So, some of the questions I've been asking.:
I start with a very broad one: What are you looking for in a game?
Then I follow on with (in no particular order):
Do you have a particular fictional genre (fantasy, urban fantasy, superheroes, hard sci-fi) that you specifically like or dislike? Any that you don't know about but are specially interested in trying?
Do you have a particular system(s) you like? Dislike?
Morality - some players like playing White Hats, Black Hats, or morally questonable hats. What's your preference? Do you have a preference for what other players in the party play in this regard?
A couple more you might want to lob in at this stage, that are kind of all connected:Electronic tools - do you expect the game to have a wiki, messageboard, or other online tools associated with it? Are you particularly for or against the use of such tools?
Position on fudging and GM Fiat?
Political plots - do you enjoy or dislike playing characters that are deeply involved in the setting's politics?
Setting conceits - do you have any particular setting style preferences? High magic/low magic, love D&D, hate Forgotten Realms, always wanted to try historical pieces, or what have you?
Personal plots - do you enjoy or dislike playing characters that have plot hooks specifically for them, personally?
Mortality: do you expect your character will never die? Might die? Will die early and often?
Adversity: do you accept level drain, item loss, and so forth as a part of the game or not?
Emotional attachment: how do you react if-when Bad Things happen to your characters?
These three are huge. And my advice is that those who don't want bad things to ever happen and-or will negatively react if they do happen are probably players you don't want in the game, if only to save you the headaches later.
Another piece of advice that has served me exceptionally well: if you have more players to choose from than you're willing to DM, always choose those who are the most entertaining and-or tend to play the most entertaining characters. That way, you get to be entertained by your own game.
