I am doing season 4 as they're released at the same FLGS with the same DM. A roleplaying effect is all I'd really be aiming for. Getting a convert or three would be fun, as would starting a session handing out leaflets on a streetcorner in Orasnou, trying to convert people to be Kelemvorites rather than followers of the Eternal Order (had to look that one up, not very versed in Ravenloft lore).
I have a wild sorcerer with a guild brewer background who played straight through a recent rerun of season 1 at the same shop. He got a part time job brewing beer at the Laughing Goblin and would keep offering other PCs homebrewed beer and moonshine(the latter was refluffed lamp oil for weapons purposes).
Usually way more interested in RP aspects than most of the table, but it is what it is. I'll see what my DM says, obviously not expecting it to mean beans at any other table. I'm not sure this FLGS submits the reports you mentioned, their recordkeeping seems pretty haphazard.
