He posted his reasons for closing the site today on his blog. Basically, he got really tired of shooting games, and he doesn't enjoy them anymore. He first started off going for 1CCs, but then when he moved to score competitions, he found the experience to be more and more futile - with wasted days off, clinging to an arcade cabinet, restarting over and over just if the score was a few points under the level he needed to be at. He says he still enjoys games in general, and will continue to enjoy other genres for a long time to come.
