The base of this game will be 1st ed AD&D.
That being said I will consider "sprinkles" from other similar games.
What do I mean? Well if there is a class/ability/feat etc from a similar game (e.g. Pathfinder) I will consider it before saying no

Players will start solo and have their own board so they won't know who is a PC or an NPC, although after a while you will probably work it out.
I would expect one post every 24 hours.
I will roll three versions of your character stats for you, you can pick the one that appeals most and raise one stat to 13.
Class requisites are in place (e.g. 17 cha for paladins)
Players will roll for their to hit and saving throws.
All alignments will be allowed
Monster races (mostly humanoid) will be allowed per DM approval.
As players come on board I will jump into the character creation process since it will be very fluid
Any questions, fire away.
