Just some recommendations I have for similar games to Metroid, whether in gameplay style, map design, or something else.
Doom 2016: I generally get a real Metroid feel from this game, from the map design feeling almost Metroid Fusion-y to the pickups dropping from all the enemies, to the rewards for exploration.
Castlevania: If it's after Symphony of the Night, it's basically fantasy Metroid with more RPG elements. Fun games.
Prey(2017): The general layout of the game is VERY Metroid. You're able to freely backtrack to go to places you weren't able to go before you got certain powers.
