Back from San Diego! I think it's time to answer a few questions.
Regarding Money: Charles is right. It's:
$1 = 1 Platinum
$10 = 1 Gold
$100 = 1 Silver
$1000 = 1 Electrum
This is backwards from DND money. The reason why is not a reference to the fact that silver used to be more valuable (if that is indeed true, I wasn't aware.) It's just because I like to be different. And in fact, if I could go back and start Flipside over I'd probably use dollars instead of coins, or perhaps a more original type of money. It's too cliche to use a DND coin system in a fantasy setting. But I'm stuck with it now.
Regarding Marvallo's Economy: It is a much more capitalist and laissez-faire type of country than Iscariot. However, prices tend to be more expensive overall. This is due to inflation. This is not what you'd first expect, but there's a reason for why this is, which I won't go into at this time.
Regarding Polly's Name: Yeah, I can see why some people might not be fans of this name. I just happen to really like the name Polly. If you don't like it, feel free to keep thinking of her as Blackbird.
Regarding the Guest Strips: I commented on these in several places, but these are written by me. So you can think of them as being canonical, even if they are guest strips. There might be a few more next week... not sure if I'm gonna write those yet.
