I'll be going with a published adventure for this go: The Great Modron March. A small blurb for you

Here's a little blurb from the back:
For those who are Planescape fans and are well-versed in Sigil, I'd love for you come in and play a planar or prime.
For those new to the setting, here's the basics: Planescape is a setting taking place in D&Ds outer and inner planes, for the most part. It has often been described as D&D meets Dr. Seuss. The entire basis of the setting is that it is a contact point for all material planes and D&D worlds, published and homebrew, everywhere. Characters from Greyhawk, Forgotten Realms, Dark Sun, Al-Qadim (which is Forgotten Realms anyway), Mystara, and Ravenloft are all mentioned in the published material; it goes even beyond these settings to say that any setting can be crashed into it.
The game has an emphasis on the metaphysical and belief. It is about style and atmosphere, as there is even a sort of slang you'll learn as you play, as people in Sigil have their own way of doing things. If all this stuff is new and worrying to you because you're not sure you want to get into a game where the setting is strange and you feel clueless, don't worry, you're the best type of player to run a Planescape game for.
That's how the game is supposed to feel. It's supposed to be chaotic and new. I encourage you to join if you have any interest, if only so you can experience the game as how it is meant to be experienced. That said, for those new, you will pick any Prime Material realm (even if you want to use your homebrew) and make a character using the basic Player's Handbook rules. I've done multiple introduction games to Planescape, so I assure you, I will do my best to provide you with the information you need.
Really quick, here are the guidelines for making characters:
- Standard ability score rolls (4d6, drop the lowest)
- Standard starting starting money (the random chart which is listed in the PHB)
- Races and classes from the PHB. If you HAVE to have specialty class or race, I'll work with you. If you'd like to be a planar, all I ask is that you show understanding of the cant by posting in here a few sentences in quotation.
- I won't be using non-weapon proficiencies, but I will be using weapon proficiencies. I don't use 2e too much anymore (usually just run it with Labyrinth Lord) and I've made more mistakes with these rules than anything else. If we want to run a rules-lite version of 2e, I don't mind at all.
Planescape is less about letting the dice fall where they may and more about your choices, your character's beliefs, and where action and thought meet.
I write. Alot. I write short stories as a recreational activity (I do not claim they are good, but it's what I do). I can get into prose without thinking, so if my descriptions need clarifications, never be shy to ask. I will strive for concision in all things. I only add detail to give you weapons against me. I'll keep it around two or three paragraphs, as I strive for immersion.
Dice rolls are still very new to me on this site. Probably go with the honor system here. Fortunately, Planescape can be amazingly dice-lite in play.
I'd like to aim for active posting with a post a day, but some of you out there have lives, which I understand. I see 3 posts a week is the norm, so I don't mind conforming to that. Optimally, I'd like to ring in some people and see where everyone is at on this and then make a decision depending on who shows interest, since I'm flexible.
I do believe I have covered everything. If you have any questions, concerns, etc., post here and I'll get to you as soon as I can.
EDIT: To make a quick idea for the thread.
- The Great Modron March, published adventure using 2e in the Planescape setting.
- 4-6 players.
- Starting at 1st level with 0 XP.
- Standard dice rolling for ability scores (4d6, drop the lowest, six times).
- PHB races or Prime characters only for those new to the setting, meaning you're playing a PHB race from one of the prime material planes. If you do not know any prime material planes (such as Greyhawk or Forgotten Realms) just make a character using the PHB and do not worry about it. If you'd like to play a planar race or character, please post here with a few quotation sentences demonstrating you know the slang in the Planescape setting.
- Starting money from the 2e PHB [ Warrior 5d4 x 10 gp, Wizard (1d4+1) x 10 gp, Rogue 2d6 x 10 gp, Priest 3d6 x 10 gp ]
- I mostly will be using the PHB, DMG, MM, The Great Modron March, and the Planescape Boxed set. I deviate from published adventures quite a bit.
- Weapon proficiencies are in, non-weapon pro-ficiencies are out. I have no set house rules at this time. I believe that house rules should be made through democratic dialogue.
- My target activity is a post per day, but I'm flexible and understand that 3 times a week might be more reasonable for those involved.
- I will not be PMing for a new forum until we have at least four people, only so we don't clog up the threads with a game that's a no go.
