I seek novelty. That typically come's from the card's premise more than it does the ongoing roleplay once the overall theme is explored. I suppose you could try to write your own cards and plan out an entire story arc for them, but unless you want your card/model writing for you you're going to have to do most of the legwork yourself.
I can hit 100+ back-and-forths with an idea that takes an unexpected turn and keeps developing, but that is the exception rather than the rule. Also, at that length, many models begin to struggle, devolving into looping. There are tools to mitigate it, but at some point you begin to spend more time rewriting and fiddling than you do actually enjoying the roleplay.
