I'm interested in recruiting new players for a campaign in James Maliszewski's infamous megadungeon, Dwimmermount. This is a really cool megadungeon –– political factions, a history of 1000s of years, etc. etc. The game is largely based on exploration and discovery; there's a lot of setting lore, and one of the goals of the game is to discover more.
We use LL Core with some house rules (and some rules that are Dwimmermount-specific).
If this sounds interesting, here's the link: app.roll20.net/lfg/listing/41001/dwimmermount
