It's true that there are two kinds of game development going on. I wouldn't call the mostly mobile, metrics driven game dev 'indie' but at the same time that kind of game development has a lot to do with the same business model.

These metrics driven developers risk more cash up front and take less creative risks. Like a Hollywood movies, they pick a genre that is already successful and twist it a little. They likely even spend more on marketing than on production.

Still, even those games (like hollywood movies) remain hit driven so you'd better have a big budget backer to smooth out the edges.
