Quick question, how many people do you know who had internet access in their homes back in 1990? Not many, if any, but it's incredible to think that Sega manufactured their own modem, meaning that the Sega Mega Drive had - you guessed it - online capabilities. Honestly, that is simply mind-blowing - years before internet, even dial-up connections, would become commonplace in the home, there existed a console which enabled players to download games and play online. Perhaps not surprisingly, the concept would never make it outside of Japan, which is why it's rarely discussed on these shores. Obviously, playing games online, and even downloading full retail releases, is common practice nowadays, but in 1990 it must have seemed like people were one step away from living on space stations. It's unclear just how successful an experiment this was, but it just proves how ahead of the curve Sega could be.
