Today, on July 31st, 2009, thousands (perhaps tens of thousands) of players will be 'jacking in' for the last time ever; once in, they will be bidding adieu to their fellow 'red pills' and perhaps throwing their last party while they're at it. If you didn't get any of those inside references, then chances are fairly high that you have not paid much attention to The Matrix and its MMO continuation, The Matrix Online. Chances are also very high that you would not know (or care) that MxO will be shutting down their servers forever tonight.
If you think about it, it's actually quite rare to see a subscription-based MMORPG go down the tubes, although that certainly doesn't mean that it doesn't happen. This year alone we've witnessed the sad demise of Tabula Rasa and saw the gates of Hellgate: London closing forever (I blame it entirely on the lack of LAN play!). The shutdown of The Matrix Online actually does come as an odd sort of surprise to me, as this is will be the first MMO that SOE has shut down, despite the fact that SOE publishes a lot of MMOs, and some of them aren't exactly the pinnacle of popularity (Vanguard, Planetside and Everquest Adventures come to mind).
