As a term, "Metroidvania" has existed for almost twenty years, used to describe a certain sub-type of action game. A game like Metroid. Or Castlevania. Y'know, a Metroidvania.
Some critics really don't like the term. They think it's aesthetically unpleasant, obscure, and inaccessible. They don't think the term should be referencing two other games, and that doing so makes it useless for anyone who hasn't heard of Metroid. Or Castlevania.
Should the term be abolished? Should we work on a replacement, since few critics have? Is this an accessibility issue? I guess this video will address those questions. Maybe. Probably.
