Are you guys kidding?
First, I must mention the system tha thas the best meemories for me is the Sega Genesis. The Super Nintendo only had Mario Kart and though that was an awesome game not enough to make it better then the Sega.
Sadly, the best of the new systems wasn't even an option. The Sega Dreamcast had way better graphics, games, capabilities, and many other things compared to the PS2 and Xbox. The only thing it didn't have is marketing. Eventually, when the system could not produce any more games it was discontinued and production of the machine and its merchandise was halted. If it had been marketed properly the machine could be where the Xbox is now. Reminds me of the Beta debacle.
