I would have liked to see all the sound and music done with FM synthesis (or whatever the Nintendo used) in Python as well, instead of .ogg files.
Games will be considered a form of art someday. And it is the whole form of an art piece that is important (i.e. the medium, inner workings, presentation). In the future, the innards of classic games may become increasingly important, perhaps from an anthropological perspective. When video games become centuries old, I feel they will be artifacts of an emergent art form.
