From the introduction: In Outer Space, there's tons of things to do. When you have a thing that you want done, contract the Space Aces! We are mostly competent, heavily in debt, and highly motivated! Do you love rules-lite no-prep sci-fi rpg games like Lasers & Feelings but wish it had a little more to it? Crave the emergent narratives of Fate, PBtA and Genesys system games without all the RULES? Love the danger of OSR games and the simplicity of FKR games? Have good eyesight and want an entire game system that fits entirely on a business card? Meet Space Aces! Space Aces is a modular system that utilizes a super simple D20 & D6 rolling system that gives you lots of interesting narrative results to rolls. A success can still result in a Cost, and a failure can still result in a Benefit... Ramp up difficulty, tension, and consequences as the mission goes on with the Heat Level meter. Everything you need to play on one business card. Do you and your crew have the Gumption it takes to complete the mission? Or will you be Taken Out like yesterday's space baguettes? Whatever happens... Adventure Awaits! User summary: The game is distributed as ten 2-page PDF documents (intended for print-and-play) and also as a single, combined 20-page PDF document.
