tight math - yesIf you are looking for a game with tight math, tight encounter design, meaningful narrative uncertainty, embedded lore and modular design the actual execution here is excellent.
If that is not what you are looking for then the execution does not particularly matter.
tight encounter design - no
meaningful narrative uncertainty - I guess yes (but that exists in every D&D game I've played so I don't understand how that is a feature)
embedded lore - a big no
modular design - yes, but depends what you mean. I love the modularity of 1e, 4e, and 5e. How is PF2e different?
If this is the list that makes PF2e distinctive your making me re-think my idea of playing the game from: going to give it a try; to: perhaps not worth the effort. You are basically telling me it is like every D&D game I have played with some bits I don't like or don't care about?
Please tell me I am misunderstanding, I just started to look up where to play!
