I get Dan's logic here on the mainline Mario thing, but his mistake was counting Mario 64 as the next mainline Mario when it was the beginning of a new series, aka the 3D Mario series. They're a completely different style of game from a traditional 2D Mario platformer where instead of moving to the right and jumping on a flag pole or a goal at the end you're navigating a 3D space and collecting Stars or SHINEs and usually re-entering the same location immediately to play a different permutation of the same stage. NSMB and Wonder are entries in the mainline 2D Mario series and it's as simple as that.
@janman maybe for Season 2 after each Thursday show gets uploaded have links to the 3 prior shows from earlier in the week for those who want to catch up on Narrative Continuity.
Then you can play Zero/Azure and Cold Steel 1/2 in any order
but then make sure you've played all those before you play Cold Steel 3 because that's when all the plots from all those games really start to come together in an MCU Avengers style fashion but JRPGs
