My favourite Metroid game has got to be Zero Mission on the GBA.
A weird choice maybe but it was my first metroid when I played the GBA, I thought the music and atmosphere was kick ass and enjoyed the simple enough controls.
For a 3D Metroid it would be the trilogy on Wii at the time.
What about you?
But that’s what I’m saying. It’s so unlikely you’ll make it out of it that when you walk into the room and the EMMI is already occupying the space you walked into blindly, it’s a frustrating unavoidable fail state.
