For those of you unfamiliar with Tomb Of Horrors it is an old Tournement Module centered around a very deadly Lich's Tomb. It is very much focused on problem and puzzle solving as a test of a player's skill to do so. So while it isn't free of combat there isn't much of it and while you can absolutely roleplay the Tomb doesn't really go out of it's way to give you interesting roleplay opportunities and your characters can very easily die as a result of a single mistake; problem solving is the meat of this module and if you feel that's not something you can enjoy this game likely isn't something you'd enjoy. For those of you more familiar with it I'd be running it in OSE since I am more familiar with it than AD&D and it isn't that far off from AD&D on which the module is based. Though I am new to GMing, I have run it once and feel that I can do decent job of running it, though again I think it requires a certain mindset to enjoy. I did make some changes to adapt it to OSE and while I will try to mostly keep it the same I am likely not going to run it word for word and when the module is unclear on specifics of how a part works I'm likely going with my best guess(though I'll try to make sure it's still fair in the sense you could reasonably have avoided that "trap" if you were more careful and/or clever). As for the logistics the time isn't set but 4pm PST on Sundays is the default. I'm PST and could generally do something 6pm-12pm on most days and likely a bit earlier on weekends. This game will probably take very very roughly around 5 4-hour sessions but that's very dependent on how people actually play. I'm assuming the goal will be to beat the Tomb so in the case of TPK I'm thinking you'd just make new characters and pick up where the others left off but we could always call that end if that's what people wanted to do. I'm hoping for at least 2 other players and think I could do up to 8 if people are willing to take up less of the "Spot Light"; though if we are playing with only a few players I'd like it if those players could handle multiple characters as the module expects more characters. Though if desired i could just treat those characters as NPCs to help with spells and combat but not for brainstorming. The only real requirement I have here(beyond the obvious) is to not have already played the Module; knowing a few things through hearing about this module is fine so long as you don't mention them in game and let the other players handle the problem solving them. Also this game would be happening on roll20.
