On September 9th, 1999, Sega launched a console that probably was too ahead of it's time in the US. While the system did die a VERY early death in the US (I blame retailers telling people to wait for Sony's PS2) in Japan, the console lasted a bit longer. The last licensed game was released in 2008, which was Border Down, a reissue. Even after all that, unlicensed games are still giving the Dreamcast love. Games like Pier Solar and Ghost Blade are giving Sega's final machine life still.
So today, if you still own a Dreamcast, fire it up and give it some love.
