It had a ridiculous library of great games, yet some how failed. Was it due to Piracy killing off the system, or no dvd support for the Dreamcast? What killed off one of the greatest Consoles ever created? Well, killed off as in the sense that only independent game developers are the only ones that work on this console still. If you look at in that sense Dreamcast is still alive, but from the perspective of Sega making anything off the console now a days it's a dead console in that sense.
