Yeah, I think it's probably good that there will be multiple adventures available through Limithron that offer a variety of adventure lengths.
- The Battle of Dead Man's Cove can probably be completed in 90 minutes.
- Buried in the Bahamas is about a three-hour game.
- The Sinking of Cthagn is probably a three-to-four hour sandbox game.
- The Curse of Skeleton Point is probably two-to-three sessions.
- And now Trapped in the Tropics sounds like it's a good three or four sessions game.
So everyone can pick what works best for their introductory adventure.
