I am aware that Puyo Puyo Quest gets a mouthful of crossovers, but I was more talking about Puyo-related crossovers that aren't using Quest as a basis, like PxZ or the SEGA characters in Banana Mania and Banana Rumble as I mentioned above, or how Like a Dragon content is coming to both Fortnite and Dave the Diver. I really want Puyo Puyo to beat the "relies too much on a gacha game entry" allegations because I know the series is more than just Quest.
Huh, I actually didn't really know that. The funny thing is, during Ultimate DLC, someone used to try and astroturf SoR on me when I brought up Puyo just because 4 was out and everyone liked it. And then absolutely nothing else is happening for that series until that new game they teased comes out...assuming it doesn't end up cancelled.
Goes to show that recency bias is one heck of a drug (I should know.)
