I also had a few questions:
1. I'm trying to understand the percentage change of success when doing skill rolls. Also because the die explodes it's hard for me to visualize this. For example, how much is a +1 increase of a skill or stat?
Percentage-wise, the dice explode on 3 possible rolls... A natural 20 (Super Nova)
or when either die rolls a 10.
Now, with 2d10, there are basically 100 different possible dice combinations that can be rolled.
So, you have 1 1% chance of Super Nova
and that would be an 18% chance of an exploding die
Basic success is 15 or higher, so your basic chance of success (with a zero skill bonus and zero modifiers) is giong to be 21% as there are 21 possible dice combinations (excluding exploding dice).
If we includ exploding dice, that changes things slightly, in that you have an extra 10 combinations that can lead to rolling a 3rd d10, and the chance of that throwing you over the top is variable depending on what the initial roll was.
But speaking VERY VERY VERY roughly, I would put the chance of a successful dice roll for the basic TN at being approximately 35-ish %
And remember, that does not include Advantages or Complications or skill bonuses or any other modifiers....
And to me, that feels about right....
