Interesting idea Malebolgia - I'd like that too.
@ Mr Peabody - good point, didn't think about that. Definitely not D10. Probably D8. Maybe even D6. Needs to be somewhere between Ally and Sidekick. I think I'd probably go D8 to give them a little bit of staying power.
@theoldscool - musketeers with PA sounds spot on. Really want to give that a go given the excellent BBC series of the same title. Imagine 7th voyage might work also, but have no experience with those rules so can't really comment. To any 7th voyage players, what's the main selling point of those rules over PA (if any?).
