It's curious how perceptions vary. I interpreted the author as trying to explain that doing crazy stuff in a video game is actually pretty normal, as opposed to drumming up drama by insinuating that gamers are all crazy. I guess they didn't take into account all the people who don't do weird stuff, but it seemed to me that the goal was to talk about those who do and emphasize that it's normal, not imply that everyone does.
I guess if you don't buy into the author's argument and know nothing of the sims, you might think sims fans are crazy. But if that's your reaction, you might also think FPS players are all serial murderers waiting to happen, so I don't know that it's going to make much of a difference.
