It’s almost certainly a positive to see Bobby Kotick (boy do I struggle to maintain this site’s cardinal rule as far as he goes ) losing influence in the “AAA” games industry; but it’s not good to see MS buying every studio they can get hold of. Both these things can be true simultaneously.
My biggest concern with MS’s rampant acquisition spree is what happens when there’a an economic downturn (as already seems to be the near future); will those newly acquired studio be subject to the corporate euphemism that is ~dOWnSiZiNg~? How many working on moderately niche titles will be out of a job and their work indefinitely shelved?
Beyond children's stuff, and entry-tier Ghibli films, I think K-On! was one of the first anime I actually watched. I'm not really sure what I thought of it, certainly don't recall much about it. Probably took an interest in Japanese media more from manga than anime; yuri like Morinaga's Girl Friends helped me realise I was bisexual.
But to focus back on anime, Nichijou is probably what made me realise anime could be worth my time beyond the odd film, that made me smile on a lot of otherwise dark days. And on the opposite side of things, I'd probably attribute Madoka and NGE with teaching me the value that anime could hold as 'art'. (I'm a sucker for an effective deconstruction of a genre.)
