The 1990s were a whirlwind decade for Sega; the company experienced its greatest highs with the Genesis/Mega Drive and some serious lows with the 32X and the ill-fated Saturn. By the summer of 1998, the PlayStation was the king of video games, Nintendo was creating childhood memories with the Nintendo 64 and Sega was without a home console after the early discontinuation of the Sega Saturn. Sega needed to answer the competition and deliver something big in order to stay alive in the console market. The answer came in the form of the next-generation Dreamcast.
