With everything else that's been tried as people have gone retro-cool, has anyone had experience doing a really old school style campaign, with the following elements:
1) A dungeon seeded campaign map, to be used sandbox style, that can potentially be mined out.
2) Campaign map and higher level NPC power players fairly static. PCs are meant to rise and rank and become the active factions.
3) Closer to 20+ players in various combinations on various days ( West Marches style).
4) Characters not necessarily assumed to be friends, but PvP element more about the race to name level and conflicts then, rather than direct, below-name-level, shankings.
Just curious. Would love to hear about how things turned out.
