…and why is it the Zero Mission version of Kraid’s Lair? 😎
Seriously, though, what are your favorites and why? I like that particular version of Kraid’s Lair because it’s so bombastic. The way it sounds, I can easily imagine that an instrumental version would feature both organs and electric guitars, which is an awesome combo.
I just really like Metroid 1 Brinstar. And Tallon IV overworld first theme that’s a remix of it.
Metroid Planets, the fanmade Metroid 1 remake that includes a room editor and a great random map generator, has a chiptune-ified Tallon Overworld theme that sounds very cool.
