I've been a listener for about 5 or 6 years, writing music for about 4, only recently (past couple weeks) started writing chiptune; partly because the limitations really push me as a musician and force me to think elsewhere without falling into the holes of my usual compositional style.
Personally I write music as a tribute to the games I like, I still am and will always be an admirer. Whever I make the music or not doesn't really make much difference.
