For me my three favourites are Dread Prime and Fusion in that order but aside from that very based list Also play AM2R I kid you not it's PEAK

I have played AM2R I just wasn't sure if I could rank it because it's not an official game. I'll say that it's definitely top of the A Tier. You seem cool btw do you mind if we add each other on discord it's easier for me to talk more about Metroid there!
