When people think of "complexity" in regards to music, they often think of instrumentation, texture, production quality. But some of the most complex music ever written - the Well-Tempered Klavier - was written in mostly 2-4 voices for an instrument with no dynamics. I think the 2-3 note limit really forced chiptune composers to focus on compositional complexity, thus making that music stand out even today.
