There should still be some. For one, Ratchet and Clank: Up Your Arsenal has recently reopened its servers for the HD trilogy's release. Madden of course comes around bringing football joy into online players' homes each year. Other than those it would be hard to pinpoint anything else still going on in online gaming. Zipper Interactive, makers of the SOCOM series, was eventually shutdown. The PlayStation 2 didn't have as wide a range of online games to speak of in comparison to today's current market.
