I never had the Dreamcast, a shame really. I am interested to see what the 720 will be like. A screen in the controller seems to be the way to go, Nintendo has done it so I can see the others following suit.
What happened to them, did the lasers die? Mine did, and about a week later, the same thing happened to my Saturn. If it weren't for collectors hording them and making their prices high, I would have replaced them by now.
