That article basically sums up why I don’t bother with the mobile market. Because she’s right, to survive in the mobile market as a “company” and not just a hobbyist who doesn’t need the income, you pretty much have no other option than to play the freemium/P2P/AD-supported game. Unless of course you have a truly original title that just blows everyone’s socks off. (Good luck with that on the mobile market) The market is so over saturated with $1 apps (that should be worth $10). There really is a “race to the bottom” philosophy that needs to change, because it’s royally screwing over developers. I’m hoping the race to the bottom philosophy gets so bad on the mobile market it causes a rebound effect and resets the price points of quality games back to a decent $5-$15 price range after everyone is sick of the $1 crap-shoot. But that’s just me crossing my fingers. I find it hilarious if you look up reviews on the mobile stores for $14.99 full games like XCOM, Final Fantasy, etc (that you would pay $40+ on the PC for!) people complain it’s too expensive, all the while they’re on their way to star bucks for an $8 coffee and $4 rice crispy treat. The consumer base on the mobile market is at the very least . . . misguided. 
Although I think it’s a bit different in the PC markets, one can survive with little to no DLC on a full “indie priced” title if it’s a really original idea that takes off. But you can’t count on it happening as a sure thing. It’s just nice when it does. 
But I can see the woes for studios like Puppygames though, because you guys have an entire team with families who need fed, people like myself only have themselves to take care of. (… and my wife of course :P) So we may be able to survive easier on a lower income because it’s not being split 3 or 4 ways. Case in point (just some more made up numbers) if Retro-Pixel Castles made $150k tomorrow, that’s enough for me to live about 3 years on. But if it’s a team of 3 people, that’s only enough for 1 year each, not giving you much time to focus on the next title and still support the current one. :o
