I now have everything ready for my first expedition in search of the Nadir, except for an Eyeless Skull. There is an option to ask another player for one. Is there a fair way to compensate another player? They can cash it in for Echoes; is there a way for one player to provide another player with equivalent benefit? If so, how does one negotiate such a deal?
Are there other "big ticket" sorts of trades between players? Or trades with a big item on one side, and several small items or favors on the other?
There is small-scale trade which can feel social or friendly or gift-economy-based. I am familiar with the Gift opportunity card, and have used it to send Second Chances, and once a Collection of Curiosities. I have received many bundles of rats and a few gems. I routinely trade menace reduction with a few regular contacts (whom I know only in Fallen London, not via FB/Twitter). But that seems like a different scale than an Eyeless Skull.
For a game which describes itself so much in terms of a Bazaar, and which links to social sites, I’m actually kinda surprised that the player-to-player economy is so low-profile, compared to, say, the "Mall of Loathing".
