Last month at Go Play Brisbane I ran a playtest of Siege with three willing guinea pigs. Thank you guinea pigs. It was a good experience and one I should repeat. Overall, I got some interesting feedback. These are two of the nuggets worth sharing.
I need to ensure the Hostage has motivation to stay in the story. Typically, a Hostage is imperiled and would like to simply escape. That makes for a dull story and uninspiring participation by the Hostage player. So I need to create some hooks that lock the character in for the duration.
By changing the dice, the story can be an hour episode from a TV show (d4), a feature-length film (d6), or an extended edition director's cut (d8). Nothing else needs to change in the rules except the dice you use. I like this a lot and will be sure to include it in the rules text.
Everything else? Maybe you can be in my next playtest and find out.
