Here's another similar report: S&W Sessions Journal: So Much for the Stargazer
The LotFP modules are quite cool and creative, but, by design, lack any inherent motivating elements beyond extreme danger and a vague promise of treasure. In discussions elsewhere people have placed most of the responsibility on the DM for integrating sufficient plot hooks into the modules. Fair enough...
This is the first place, however, I've heard people criticizing players for a lack of adventuring spirit.
I'm not sure this is a very compelling discussion topic, as player personality is one game parameter DMs and module writers have little control over. I'd be more interested in hearing how various DMs have effectively integrated the LotFP modules into their ongoing campaigns.
