Can you come up with new names for these "genres" that are not completely retarded?

Metroid was influenced by Zelda. Castlevania and Metroid are half-siblings

Adventure
Roguelike
Action

Next

action platformer
1guynocontinues
action

garbage games

there I did it.

Castlemania

Nethackvania

Devil May Cry 3-like

Action platformer fits more for something like megaman i think

Adventure Platformer
Roguelite isnt a genre
Character Action is fine

why did these become problems in the first place?

true. map platformer then. one user already took exploration platformer

Why would you want to? The name communicates the genre, which is all it has to do.
