Hey there, not sure if it would fit your schdule, but i want to start a game in 5e that follows the old 1e formula of dungeon focus. In 1e, roleplay happened, but inside the dungeon, under tense situations. It was not aimless and in town. Town existed to recoup at while you went into the dungon, which was typically massive. The first games ran by gygax actually were just dungeon, nothing else at all. You met people, rested, healed, fought, died, gained new party members, all of it while dungeon crawling. I would use the 5e system and run a game that exists in a world but uses a large focus on exploring a dungeon of some kind. Combat would be a huge focus, as would dealing with traps, exploring and searching rooms, dealing with puzzles and things that block acess to other parts of the dungeon, ect ect. One dungeon could take as many as 5 or 6 sessions to fully explore or escape and you could go from level 3 to 5 or 6, or more, easily enough. The purpose and what your doing there would be tied to what the story ends up being about. Trying to run it on Friday nights at 9pm-1am, if that dont work the other day is Thurs nights at the same time frame.
