For Experienced Players
How This Game Approaches Play
The design position
Under Oath is closest in structure to AD&D 1st Edition, used as a baseline rather than a constraint. If you know that system, you have a workable frame of reference. What differs is the emphasis: rules support the world rather than define every outcome in advance. Situations are read in context, and judgment carries more weight than procedure.
This puts it in the same family as the Old-School Renaissance and games like Ars Magica — interpretive, consequence-driven, adjudication-heavy. It is not a blend of those approaches. It is shaped around its own priorities, particularly the role of obligation in play.
What feels different
Resolution and Uncertainty
Not every situation goes to dice. Some outcomes are adjudicated from context. The aim is a result that fits the situation, not one that follows a preset path.
Consequence and Continuity
Decisions persist. The world responds over time. There is no reset between events.
Character and Identity
Characters are defined by what they do and what they are bound to, not by optimised builds. Progress comes through action, reputation, and obligation.
Obligation and Standing
Oaths and commitments constrain choices and shape relationships. Breaking them has effects that are social as well as practical.
