Man marries a videogame

I went "whaa?" when I read this article. I can only link to the article since there are links in the article as well an embedded video. A man basically marries his videogame ("Love Plus") girlfriend. A digital girlfriend in the videogame, not someone you met during Guild Wars or WoW or something. Not even an avatar in a game like Second Life. A digital girlfriend with no human behind her, controlling her actions or moods or dialogue.
