The sticking point for me with the term wasn't that Metroid popularized the game genre first, it was that Castlevannia had already established itself as a series of level-based action platformers beloved by many well before SotN, so I always thought adding the "-vannia" at the end of the term seemed odd and sort of ignores Castlevannia's origins. At least Metroid was from it's inception, a Metroidvannia. Although, I do concede "Symph-troid" doesn't sound as good.

It's also just good marketing to give credit, these are two accounts that likely have a lot of cross over interest to a specific audience, why not cross-promote and increase you followers?

I was always more of a "Open Your Heart" kind of guy.

Wow, what a risky move to lift that shot from Kabernari Iron Fortress. Anime studios have been known to be protective of their intellectual property and that anime is pretty recent too.

And they even announced it on July 1st (A Tuesday).

Oh yeah, they had that arcade cabinet in the game room at Otakon last year. It reminds me of Gals Panic.
