Series in order top to bottom.
Megaman - OG, 2D Megaman or Megaman X. I want to beat bosses and get power ups. None of this free-roaming or Legends type of stuff.
Castlevania - OG, 2D vampire slaying. Let me whip the shit out of the undead. No need to whip in 3 dimensions. 8 ways was plenty. I really fell off after bloodlines. I need to play Symphony of the Night.
Metroid -OG, 2D lonely exploration. I just want to kill Mother Brain and get off this planet! The Prime games sucked ass. Metroid isn't 1st person. Pfft.
That's how I feel about the series. With that said, Super Metroid is the best game.
