My two-year-old son said said something interesting yesterday. He had just made his own MOG character for the first time - surprisingly easy, and this was EQII, not WoW or YPP - and he was running around and figuring out targeting. He highlighted a snake or a rat or something, and I pressed the 'attack' button. The combat sequence scared him, though, so I turned his guy around and ran off. But I did that only after standing there with my mouth open for a second. Because he didn't say 'turn the game off' or 'help my guy' or 'what do I do'. He said 'Get me out of here.'
Perhaps because of his still-uncluttered appreciation of reality, he was already mentally immersed in the virtual world. He was already in there.
Nate and others have talked about their kids. Anyone else have child or family stories?
