Very cool. I don't D&D, but getting to read about the interaction of human social behavior and game design is interesting.

You bring up improvised theater which actually does have rules, but very few and it's more important to follow the spirit than the letter. The few rules end up working because you can't effectively do anything without depending on other "players".

What's typical bad behavior for a bad table-top rpg player?

Someone help me! I'm trapped in this room. I can't find the key. All I have is this ax and a rocket launcher.

I was always curious how Nintendo missed the potential in DMA.

I've only played the first one and that was 5 years ago, but my mind keeps coming back to it when I think of great gaming experiences.
It was immersive, atmospheric, and polished. I think it's about time I really give the sequels a try.

Yeah, it won't be because of these new motion-control devices that Wii dominance would be broken. Wii will only fall if it turns out the more casual audience Nintendo has been courting loses interest.

However, the announcement of these new motion-controllers is important because it says this is where gaming is going. There will still be non-motion control too, but now all of the Big 3 are going to be finding ways to use motion-control to get the casual and the hardcore.
