There were other people selling stuff too in other games (Watto, the Fetts, Schlindler, Mundugus etc.)
OP says: "There is, in theory, no limit to the number of players, but if you've only played a couple of games and/or have never been mafia then clearly you'd be in an unfair position if you were in this one. So I'm expecting a relatively small game." Now I dunno what that means, but someone who's played a lot of Mafia should be able to play.
I've surprisingly been town for most of the games. Just one mafia and one third party in there I reckon. Been mafia a bit more often in Filler games. Mortal Kombat - Kung Lao (Doctor) Star Wars 1 - Lando Calrissian (Driver) Star Wars 2 - Padme Amidala (Search for Ani and get in a QT with him) Escath Plays - Sonic the Hedgehog (unkillable blue) Doctor Who - K9 (Can either Track or Watch. In a QT with some girl) LOTR Mini-mafia 1 - Arwen (A type of Nurse/Bodyguard with percentages of success) X-Men - Jean Grey (standard townie that eventually turns into third party serial killer) Harry Potter - Bellatrix Lestrange (Roleblocker + three items of information about a town player) Jurassic Park - Ellie Sattler (Nurse) Battlestar Galactica - Dee (intercept QT messages)
Looking back at it I've been 3rd party a few times. GOT: Can't remember DW: Sontarran SWII: Watto JP: Brachiosarus
Need more people who wouldn't immediately be clear. Eds, Gazza, Furball, SmellyStuff, TheShiv, Veri, Ari, Bedsey, Eddie, Phlegm, Starris would all be good.
I swear me, you and Harps were a maf team in like 3 filler games but none of us are ever maf in themed games.
