Fantasy d20 is a small d20 game that is quick to learn and easy to change. Signal Lost is a survival horror game with no twenty-sided die. A check rolls a pool of six-sided dice and counts the 5s and 6s.
Your own game system
The in-app editor has a form for each part of a game system and a live character sheet beside it, and it only saves a draft that works. Your game systems are stored with your saved games, and updates leave them alone. A game system you download can’t run code on your computer.
What isn’t included
Only freely licensed material comes with Aetherboard. Nothing from unlicensed books is imported or accepted into the shop. Aetherboard is not affiliated with or endorsed by any game’s publisher.
Both rule books are in the Library, with a page for each class, species and background.
