Is it considered on-topic to ask questions about Sirlin Game's Pandante on Poker.SE? On one hand, it is very much a "poker-style" game, using a great amount of rules from Texas Hold'em and X-Card Draw, and clearly being inspired by these games in its design. On the other hand, it uses a custom deck of cards, has many dissimilar rules as well, and its existence is even a sort of snarky stab at being "better" than poker, which could generate offensive community arguments. At best, it's a valid variation of poker and worth discussion; at worst it's a completely different game that is off-topic.
It's a good thing that you asked about this.
I'm going to take the "it's offtopic" side because, from what I can read about it, the differences from poker are quite large. They have very few things in common. Just like the thing that basketball and tennis have in common is that a ball is involved.
I am however open to other opinions, if you think that it should be ontopic.
I believe that Pandante should be on-topic here at Poker.SE.
I find that the similarities to the games that inspired it are more common than the differences, and the core of the games are very much intact. I feel that the games test the same core skills, and that questions about such skills would be very fitting and not at all out-of-place. For instance, one might ask about the odds of getting a Rainbow Straight or a Floosh in a given game-state - although these are hand types unique to Pandante, the nature of the questions are not substantially different from questions about Texas Hold'em.
