I look forward to the video that covers this one.
Seems like somebody already made a quick overview on what everyone was saying on Youtube
http://www.nicovideo.jp/watch/sm9568309As for the problem of fame corrupting ZUN or the games that he makes...
Personally, I think it's highly unlikely for that to happen, since He's seen the fan population explode
and even made public speeches at the uni that he graduated from.
He's just gotten way too popular for certain people in... what? The past 8 years?
Same reason that I don't think any companies or studios will try to buy Touhou off ZUN, since if they do that, they'd get a bad repetition...
and you know what Japanease fans could do when something horrible happens to stuff they like.
Besides, I'd think that he would rather drink beer than care about all that.
