I love these games and I think the soundtracks are underrated as an essential part of their appeal. I’ll Start with one:

Tube of Medusa from Ecco2: Tides of Time.
Personally, I think the Sega CD version soundtrack is… fine, but it has a different composer. If I remember correctly, it;s the composer from the first Ecco. In my opinion, it’s inoffensive, but completely forgettable.
EDIT: I have edited the topic to include older stuff.


all the MegaMan on the NES
The Thunderforce III and IV, the 3 (yes, three, including the experimental soundtrack of the third!) Streets of Rage on the MegaDrive Anything Nobuo Uematsu on the SNES (Final Fantasy IV, V, VI, Chrono Trigger, Actraiser, etc.) and U.N Squadron
Soldier Blade and Final Soldier (and Air Zonk!) on the PCEngine (that a small part of the world calls TG16 for some reason?!)
