the double entendre is really strong. his art skills are very notable, and the memory thing manifests in a way that I don't think really reflects onto other players! the recall thing isn't an element which is like, explicitly unique to datisi and only datisi, but there's like. there's a different thing here. bear with me.
he's not a meta heavy solver, but the way he's able to draw linear comparisons to past games where the bulk of players don't see them is fairly effortless IME.
there are some of players who are unfun meta tryhards - datisi isn't that.
any d-list player can ask "why are you different in this game than you were in mini normal 192737 or whatever" - datisi isn't that.
there are plenty of players who can say "I read this person this way for this reason but I am hesitant because they have a wide scumrange" - datisi isn't that
when he talks through reads and publicly solves it isn't like he's necessarily using his power of memories to snow players down in meta. it's not like he's metacasing stuff just because that's a thing he can do to be cool at mafia. there's an absolutely natural way that he draws from his impressions and experiences with other players bleed into his interactions with them - and THAT is the quintessential datisi experience.
Noraa title is definitely accurate, and pretty adequate.
