Retrogaming with Racketboy has a piece looking at some of the console-defining titles
we miss from that little white box. From the article: "Phantasy Star Online - Sega was one of the main pioneers in online console gaming. While they had modest online offering with both the Genesis and Saturn, the Dreamcast was the first of their consoles to have online capabilities built into the stock machine. The Dreamcast came standard with a 56k modem and also had a (expensive) LAN/Broadband adapter available as an upgrade. Phantasy Star Online paved the way for Sega's groundbreaking online network and for later networks like XBox Live."
