The Saturn has online games. But anyway, Saturn had an IRC-like chat to chat with people you had went against online and a web browser as well. All of these things still work to this day.
Muttfox once came up on #cult using the saturn, as I recall. However you need a modem emulator for it nowadays, and who knows how compatible their browser is.
