Look at all the pretend money we've raised to free pretend slaves!
This reminds me of a scene on a wild west game where they were doing a "date the prostitutes" auction (yes, really) and the pretend numbers got just far beyond believable for the setting. It's good to see this go well, because it can go so, so wrong.
was that a roster based game?
No. It was ages ago; more than a few ages, in fact. Almost every scene I've seen involving an auction turns out to be no more meaningful than some colored brains in jars yelling out "Fifty Quatloos!" in, e.g., a wild west setting.
I've always been envious of people who find this fun, but it does nothing but break any suspension of disbelief for me. It rather sucks.
