Well, we did a first playtest of my game last night.
Basically it all went well, people had fun and so on (although I felt like it took a little while to get going).
Lots of changes to be made to the rules, of course. I expected a fair amount of that - some of the changes are ones that I thought I'd need to make, even. A couple of things didn't work out as expected but should be easily fixable.
My big problem, which I don't have a solution for, is that I'd like to reward in-character interaction with the crew, other player characters and assorted people all over. However, I'm not sure how to do that. Maybe giving a free new/changed relationship with the character concerned for doing this interaction would be easiest, but it's not terribly exciting. Hmm... perhaps something more like, if you play a scene with another character, the next time they are involved in a crisis you are sorting out, you get a bonus from them? Any thoughts/suggestions in comments will be appreciated.
