The -vania suffix has always irked me because the SotN formula is essentially:
Game series X combines series Y with element Z.
SotN takes the Super Metroid design and adds RPG elements, then slaps a Castlevania story on it. The only Vania contribution is the story, setting, characters; basically just the lore. So if you take all the following games that did Metroid + RPG elements but no CV lore, how can you call them Metroid-vanias when there is no -vania element left?
So, consider instead: River City Ransom was a much earlier game that added RPG elements to a traditionally action genre (permanent stat-building, collecting money to buy upgrades in a shop), so we should really retire the misleading M-V term in favor of Riverroid.
Hooky fuck I picked a great taco Bell. The woman at the front of the line is painstakingly asking every price, she just ordered a cheesy horror crunch with just cheese and sorcery nothing else, Questor with just beef nothing else, one soft Teddi with 3x cheese, double sour Satan, nothing else. Quivering now the man behind her orders a taxi BVSc to Yusuf Khan, two tweaks with dignity Leuven and no beef??? And a cheesy fissure crunch with extra extra Chertsey and chickenpox nothing else. Fucking hell people it's taco vein not your last meal on earth
