You only play Dreamcast games like Sonic Adventure on your Sega Dreamcast instead of Sega Saturn.
Yes Sega still makes games but not necessarily for DreamCast. The leaders at Sega realized that they can't compete with the other major players in the console market. So they switched to making games and phased out the console for the Dreamcast. The games they create are made primarily for the other game consoles. The Japanese market may still be open to game production for Segas Dreamcast.

The aftermarket for Dreamcast games is not significant, especially when compared to Sega's previous console, the Saturn. Most Dreamcast games were produced in sufficient quantity to not be considered rare, although a few Japanese titles can run you up to $1000.
Unless you are considering doing a bizzarro mod to your dreamcast, you cannot.
