Heck, Metroidvania used to just be the Metroid-like Castlevania games to distinguish them from the older, stage-based titles, dubbed Classicvania, now its a descriptor for just about any game with a interconnected world and progress that’s gatekept by unlocking new abilities, regardless of the underlying genre.
Also, in my mind, Bullet Hell is any time the player finds themselves in a situation where there’s an overwhelming number of enemy projectiles in play…
As for Rogue-like, Can’t say I blame people for dropping the text-based and dungeon crawl aspects from modern definitions. Procedurally generated games with perma-death is already a pretty specific combination, if definitions hadn’t been relaxed, it would likely be a dead genre only discussed in communities such as this one… Heck, the definition relaxation might have been a revival as I’m not sure I had ever heard the term befor it was being used in the newer, looser sense.
Also, as an aside, is the Scott Adams mentioned above the same Scott Adams of Dilbert fame, whom I learned via a recent post from Scott Alexander died recently?
