What you say about their top grossing apps is correct. But your analysis of the company's financial health is very incomplete.
1. They have consistent revenue and profit decreases YTD quarters. Forget about increasing or accelerating rates of growth, they're declining. Really bad for any company, I mean really, really bad.
2. Yes, they have top grossing apps. But guess what, these are mostly Funzio titles. Which they paid +$200 mil for over a year ago. They're close to making a profit on these titles (MW, CC, KA, etc). but haven't.
3. They're Asian titles are bleeding them money. They are losing growth in this market and its their biggest.
4. They're North American / European revenues and profits are rising, these are from mostly their Funzio titles (MW, CC, KA, etc.). Notice the massive gold events in the past few months? Its to dampen their hemorrhaging declines in Asia. They're bleeding their North American / European customers to try to help short term balance sheets.
5. Please view recent financial quarterly reports:
GREE sees FY14 Q2 sales down 7% to $310 million, but international sales rise to $72 million

Dip in coin consumption sees Gree's earnings tumble

Both articles are from this month. Last quarter was not any better.
This company is in serious trouble, and don't fool yourself or others by thinking "top grossing" titles means their financially fine.
