Original: The Dreamcast was the first entry in the sixth generation of video game consoles and was released in late 1998 , before its contemporaries -- Sony 's PlayStation 2 , Microsoft 's Xbox and the Nintendo GameCube .
Simplified: To help the Dreamcast sell even more , Sega told many stores to show some of their best games to customers , like Soul Calibur , Sonic Adventure , Power Stone , and Hydro Thunder .
