Playtest went well tonight. I'll be polishing up the adventure/setting guide I used, fixing some errors, and posting it and the core rules up here.
I added in a secret mission system off the script, and one of the players got lucky and managed to just not get shot (not "dodging", just not getting hit) while successfully taking out a VIP and one of the other players.
Thoughts:
Solidify combat difficulty levels. Having two rolls and a standard damage amount seemed to be more fun than rolling damage.
Add in a critical hit/miss system. My players were really sad not to have one.
Add NPC stat blocks.
Flesh out some rules for the setting.
One page modules worked really well at keeping rules on topic.
Add examples to text where possible. I probably don't need two appendices in the ABACUS section.
