Thinking about it, I guess ... most of my music has been heavily, heavily influenced by all the NES/GB music I listened to growing up...
Everything I've written has even been structured similarly: a main melody line, a countermelody, a bassline, sometimes some drums (usually even only a hat/some noise that sounds like a hat, just like NES/GB could make), maximum 4 or so layers/channels, and kept short and looping...
