I enjoy the Forged in the Dark system for adding a bit more granularity than PbtA. They deliver the "fiction first" while still fitting enough crunch in to satisfy my gamer/numbers side. At the same time, I had been pondering how to bend the Cypher system to mecha combat a la Battletech. When I stumbled upon this Kickstarter via RPG Academy, I found that someone already did the job, and by orders of magnitude better!
Just as with BitD, I feel like Beam Saber strikes a balance between a) Letting the fiction happen in the heat of the action, and b)giving me a bunch of gamified knobs and sliders to play with during the downtime between missions.
Kudos to you, Austin Ramsay. I can't wait for the full version to come out!
