Thank you for your answers, PhantomPistoller, and welcome along, RubySlippers.
I personally prefer to avoid having 10+ classes on 1 character if possible. I personally prefer playing a Core Class a long way, or for a gestalt, playing 2 core classes. I am not much of a multi-classer in general, and my NPCs may reflect this, but if you are alright with that I would not mind running this game.
I have a fair sized number of 3.5 Edition D&D books, as well as some 3.0 books and Pathfinder books. I don't touch 4.0. I also have some Forgotten Realms books, and Eberron books, but I'd prefer to avoid setting-specific books at least. The reason I mention this is I'd like to talk ab it about what books could be looked through for materials, and what people would want to ban from the game. Personally at least, I'd want to keep all "Dragon Magazine" content out. I don't have them, and can't check it if someone is cheating. I doubt anyone here would really want to cheat but it takes 1 bad apple to ruin an entire game sometimes.
I'd prefer to leave the erotic material to the players themselves, if they want to flirt with a barmaid, I can NPC her but she might be world-weary and not too keen on responding in a grimdark world. Nonetheless, the above example of a Temple of a Love Goddess was a good point, such places would certainly warrant their share of attention.
As would breaking into an evil wizard's tower only to find him in Bed with a Succubus and staring at the adventurers in shock...
Which might be because they just broke the magic sigils keeping the succubus from gulping down his very soul, by pushing the door open and scraping the chalkmarks in the floor near it.
Anyhow, I am not against the idea, and I could try it. I would like to know if there's more interest before starting. I think that I'd appreciate having a 3rd member for the party still before giving it a 'go', and 4 would be best. 5 or 6 if there was that much attention, could be negotiated with the group.
I've tried to run some D&D games before, the action seems to die out when someone goes missing in the middle of combat though. For that reason, I'd probably insist on NPCing a character if their player is gone too long, to keep the game from bogging down too much, especially with a fight scene.
But for a thought, here's one post to think about, as a possible game. To see if the atmosphere is right and what not.
The Tradegate of Trisholm
The world has become a dangerous place, and the stranger may be a threat. Little hamlets and villages quiet down when a rider passes by. There are few places that hold up the civilization's presence though. Towns dot the countryside here and there, and old ruins stand where borders of kingdoms used to lay. These days, the rule of those kingdoms is rarely felt, so weakened by the years of wear and tear that their grasp on their own lands has been lost, and rarely felt.
The sun was setting over the lands and the little town of Trisholm was preparing for the nightfall. The few merchants that had followed the old trade road had already settled into the local inn to wait until daylight to continue their travel by morning, the guards had been sent to watch over the walls surrounding the town. The west and east gates were being closed when a guard on the wall shouted at the west wall, rising his voice. "I see travellers, hold the doors a little longer."
So they did, but not without calling a few more guards near, just in case. The region was dangerous, and they wanted to know what was coming in, Whoever it was, would have to pass by the guard sergeant before being allowed into the town. That was the rule, after the sun had set in the horizon. These strangers came far too close to nightfall for the guard to give them a gentler treatment.
Chainmails kept making thier ringing noise as the guards set up ready to slam the gates shut and bar them with the sturdy beam once the travellers were in, the additional guards standing at ready with their hands holding onto their spears just in case.
