Apparently a Gamasutra writer had been
tipped that if Bioshock Infinite was not a MEGATON seller, Irrational was toast anyway.
The companies don't have to change their views, at least to one that benefits "The Art." Speaking outside of first party, as in Japan the West seems to be dominated by companies like EA and Take Two, perhaps Ubisoft and Warner Bros., with studios dying over time or being absorbed by publishers. The same in Japan - there are about six big Japanese companies: our lovely SEGA, Capcom, Bandai-Namco, Square-Enix, Tecmo-Koei, and Konami. Speaking about Japan, I've seen people comment that they were behind in development practices compared to the West, but I don't know much about that for sure.
If you continue to value high risk high reward projects and believe that they'll pan out for you, or if they have in the past (for you or someone else!), when things go wrong it's going to appear to make sense to lay off people, cancel new (perhaps ambitious and creative, perhaps soulless and derivative) projects. Smaller studios and projects are less of a risk than mid tier budget projects, erasing the question of whether or not its an established brand and what not. Intense stratification like we can observe here is bad in most any context I think.
There's also a budget problem (too many people working on Assassin's Creed games and Resident Evil 6!), but that budget problem is tied into the blockbuster appeal for some games. For something much smaller, you may want to look at
Skullgirls. It's also worth considering that offices for game companies are situated in places that cost a lot to live in.
Really, it seems like most people know better. Though you have to question how ill-gotten it is, the gaming industry is generally profitable; I've read once that it's more profitable to be in games than in movies. There's this
NaughtyDog interview calling for diversity (AAA, midtier, etc.) and
this highly compelling interview segment with SEGA's Ethan Einhorn saying consoles aren't dying and diversity is good. It's just a consistent management problem, with too many elements that are rotten, like QA being awful.
edit: it's worth noting that there are elements that are organic and elements that aren't. The mainstream gamer's tastes change. There isn't anything fundamentally offensive about Angry Birds existence as a game,
it's just that few mobile developers will ever be anything like that.
