01
What is it about?
2d20 supplies a shared foundation that each game reshapes for its genre. Star Trek Adventures emphasizes exploration and cooperation; Achtung! Cthulhu mixes pulp action and horror, while Dune adds its own conflicts. They share central ideas and mechanics, but their rules and play experiences are not identical.
02
At the table
Roll two or more d20s and count results meeting or falling below the target. Extra successes can generate Momentum; each adaptation defines how to spend it and handle threats.
For module creators
Publishing modules
Programme or platform
World Builders permits publication of games, scenarios and supplements through DriveThruRPG after accepting the programme agreement. The creator receives 50% of sales; independent commercial publication involves another contract, with an application and different percentages.
Conditions
