Hi. The DC is not dying at all. If SEGA dies, the whole world of "console" videogames dies. They bring out the innovation in videogames. If the system indeed died, I would be happy with my 30+ legal games that I bought Import/Domestic. Games like Samba De Amigo, Daytona USA, Guilty Gear X, F355, Grandia II, Skies of Arcadia, PSO is a good enough collection of games to die by. Right now the Japanese market of SEGA is dying and that's not clearly the case in the US. To me it seems that the Japanese gamers are somehow jaded by their choice of games since they camp and wait in line for days when Square releases a NEW Final Fantasy. Each FF game gets worse and worse in each installment.
Just remember, it's all for the love of the games. Whether you own this system or that, the one's that bring you the most fun are the one's to keep. Ask me to reccomend games if u are new...
