All the games I have have excellent graphics, very realistic textures, and lots of detail throughout. They are definitely the best I have seen in a video game console, and definitely better than some of the PS2 games I've seen so far. All of that brings us to the future of the Dreamcast. I knew going in that Sega had decided to stop manufacture of the hardware. They claimed that games will still continue to come out as long as the developers want to.
Many good games are still on the horizon, but the future is definitely uncertain after that.
But to me, the draw of being able to get a 128-bit system as good as the Dreamcast for the low prices they have now was too good to pass up. The initial cost is low, and the games are cheap. Accessories are also dropping in prices quickly. Those are all available pre-owned for less. For that kind of money, you could have a DC, an extra controller, mega memory card, gameshark, and at least 5 games.
