Are cool, but if you base your console (Whoever makes it) on 5 minute wham, bam, thank you mam arcade fest's the console is doomed to fail. The Dreamcast has some great games, but aside from Shenmue weren't all Sega games of the Arcade type (ie Last a little over five minutes and then it's over)
If Sega concentrated a little harder on games like Shenmue, maybe the Dreamcast would still be a strong player and not on the sidelines like it is now.
Sega DO make great games, in fact they have made some of the greatest ever IMO, but after the huge success of the Mega Drive marketing campaign (Here in the UK at least) they either thought they owned the market and rested on their lorrals or they simple lost the plot when it came to advertising.
Either way it's brought about the demise of this once great company and now I've heared recently that Micro$oft is probably going to buy them out.
