Hey David!
Was looking through the rules and it took me a reread and while I did understand most of it, there's some confusing language for the Event Die system--I recommend saying something like 'use the higher die' etc. And I think the 2/4/6 results could be worded better--I see that in the expanded event die system 1, 3 and 5 have keyed results, but in the regular one they don't and that can be confusing.
