I don't have numbers on this, but I'll bet the percentages on mobile studios struggling financially are even worse.

Plus, there may be too many games, but I'll put an asterisk on there that there are too many long games. When so much of it is designed to keep you coming back to this one particular game over and over again, there's less room in your life for other games that you otherwise would have been willing to buy. I've got a list of 14 games that came out this year or have release dates this year that I'm interested in getting around to still, on top of the 8 games that I've already started or finished, plus another 8 that are expected to come out this year but don't have release dates yet...and I'm still going to spend a few hundred hours across three different fighting games that I've been playing for years.
