Hideo Kojima commemorating the completion of his last MGO (Metal Gear Olympics) event.

As the Summer Olympics kicks off in London, Hideo Kojima posted a Tweet today likening the Metal Gear Solid series to his own sort of Olympics.

Wrote Kojima: "When asked what the MGS series is to you, I once responded, 'It's like the Olympics.' A big event held every three or four years. You devote your life to the major goal of a fight on the world stage. You think of nothing beyond that. The latter half becomes difficult, and you think that you'll retire after this. But after release, you think about the next tournament."

We may find out about Kojima's next Olympic event at the Metal Gear 25th anniversary event on August 30.
