They are not to my taste, primarily they lack task resolution guidance/rules so it is all dependent on the whims of the GM. I want things like outcome options a la PbtA or task+intent negotiation from Burning Wheel in the rules. Also the systems are very sparse with character abilities, a non-magicuser in combat essentially just attacks. All in all not to my taste. To many others tastes though.

However I get everything he publishes as the word building tools are pretty frakkin awesome. Tools for prepping equally good. His One Page (thing) collections of tables I put to really heavy use. Unlike many other tables the outcomes from his are pretty much immediately useable.

If you have the time just get the free versions and look through them. These free versions aren't really cut down text only versions, they are the full game. Minus some "extra" material.
