Exalts and Excellencies-- playing Exalted using Mutants and Masterminds rules

[Friv]

Ah, gotcha. How about spending, oh, let's say a hero point to gain a circumstance bonus equal to 1/2 your Virtue to a given roll, as long as it's in line with that Virtue? Eh... maybe not as good as just spending a HP to reroll... hmm...

Possibly set acting in accordance with your Virtues as the trigger that grants Hero Points, rather than requiring players to behave like traditional superheroes? That way, you're keeping the idea that Virtues constrain your behaviour and providing benefits, while adapting it to your different system.
