A game is not an embedded system, a video game console (or a router, or any special purpose computer) is! I see what he means, but it shouldn't be call embedded system. What about "embedded world", "contained world", "digital ecosystem"? I don't really like those names, though, sound too much from a 90s 'hacker' movies. What names would you use?
