| Liking this a lot. Seems to allow for a wider variety of styles, e.g. time pressure vs none, total vs partial victory.
One simple suggestion for your Advanced Options: While I applaud moving a way from a successes vs. failures model and just requiring a threshold number of successes, I think it would make sense for certain failed rolls to actually count as a failure, by deducting from successes. Not standard failed rolls, but ones representing very risky attempts or counterproductive actions. For example, trying Intimidate on the King may be extremely risky; if you succeed on the roll it does help but if you fail it's worse than failing other checks; you really offend his majesty and you have a setback you need to make up for. If these cases are rare and usually clear or hinted at to the players they should be well aware of the risks so that it shouldn't come up unexpectedly or often so as to screw up your math.
