I loved the game!
I discovered FIST recently and when I think it could work as a skirmish game, I'm surprised to find out that they've done it before me! God damn!
But seriously, FIST Tactics is really cool. I imagine it should work fine for playing a Shadowrun skirmish.
I missed partial cover in the rules. It could at least go along with the optional rules. I also found the choice to remove partial successes curious. I wonder how this would look with the tracionals 7-9...
Anyway, I can't wait to make my own skirmish hacks based on FIST Tactics. Congratulations for the game, Kameron!
