One of the comments in that Joystiq article made a very good point: one of the bigger reasons why people are downloading TG16 games more than Nintendo and Genesis. Unlike Nintendo and Genesis, Hudson doesn't repackage their games for newer consoles every 5 years. The TG16 games were only released once on the TG16 and never repackaged for future consoles.
Let's also not forget about the excellent multiplayer opportunities for Bomberman '93 and Dungeon Explorer.
It leaves me thinking that maybe...
just maybe, the TurboGrafx-16 will regain its long lost popularity within the mainstream video gaming community and perhaps even surpass it.
