Oh well, if she said so, i'll give her the benefit of the doubt, although the words "some testers" and "part of" seem to me like... excessively unprecise.

Well, that right there means so much.
Hell, if all I had to do to get recognition and support was to go against the grain, I would do it a lot more often.
Seriously though, conditioning is great. But it is also pretty gosh darned specific. And the real world doesn't have immediate rewards, so it will need to be constantly reinforced.
Best case scenario: We get a bit of brainwashing going on that says "Doing 'good' things is good". But we already have that. Turn on pretty much any TV. Hell, turn on kid's cartoons, we are doing the brainwashing early.

Well, I watched the whole thing. At first, I wondered whether the whole thing was satirical, but it actually makes some sense... Some.
Her overall point seems to be that games can inspire people to be more proactive in real life. That might be true, for some people and for some games, but outside of the specific games that she describes at the end as part of her own designs, I would think that only a minority of games and a minority of players would actually change their real-life behavior significantly for the better as a direct consequence of gaming alone.
This is appropriate, I think, because only a minority of gamers will want to play her minority of games anyhow.
No, social proactivity is not so easily learned, especially by the majority of gamers who are adults (if they have not already learned). If anything, gamers are LESS motivated to improve Real Life than other folks because of the amount of time they spend trying to avoid it.

Of course by playing games, we are saving the world - since saving the world seems to be the theme of many video games...ESPECIALLY in the RPG genre. ;)

My wording is unprecise, mostly because I didn't bother going back to hear exactly what she said.

Well I think some of the newer games moral systems reflect that a bit. Like Fallout 3, you nuke the town and you get lots of money and a really nice house. You save the town, you don't get anything but enemies and a pretty clunky house.
I like it better when video games morals reward bad things and not good things, because normally only bad things get rewarded, the reward for the good thing is the good thing itself.

that was a rather awesome presentation... not sure why people are writing it off.
