What was the name of the first games console created by Sega?
Sega Mega drive
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.
