Mass Effect: Expanded Universe
I Should Roll uses a homebrew tabletop roleplaying game system called Mass Effect: Expanded Universe, created by Kaya Renwick and Evil Atlas. The system draws inspiration and mechanics from Dungeons & Dragons (5th ed.), Blades in the Dark, Fate, and Powered by the Apocalypse, as well as Kaya's and Evil's imaginations. The primary mechanics are d20-based skill checks and d6 pools for combat.
We're still tweaking the system, but watch here for a released PDF in the future!
