For a long time I’ve struggled to create my own game mechanic, to no fruit (good tasting fruit, at any rate). Then it struck me: why not start with my all-time favorite game system (Mutants and Masterminds) and add my favorite game mechanic (roll results in games that are Powered by the Apocalypse).
One Caveat: I wanted the feeling of the game to be one of contests, because that’s the wheelhouse I’ve been playing in lately. What I mean by that is players and GMs (or other players) roll dice against each other to determine the winner.
Here’s what I have in mind:
- Determine actions for PCs and, if appropriate, any relevant NPCs involved.
- Roll 1d20+mod for the PC, and 1d20+mod for the obstacle/NPC. The winner succeeds at their stated action and gets to narrate what happens.
- Add the loser’s resistance to their result. If the total is still lower than the winner’s result, the winner succeeds fully. If the total is higher, the winner succeeds at a cost.
“At cost” means that the loser gets to embellish on the narrative and create a minor effect (lowest degree possible).
As a general mechanical concept for a game which focuses on delivering an old school feel (mechanical simulation) with a new game experience (“story forward,” no initiative, etc.), what do you think of this?
