The Charticle: The subtle similarities and differences between Google Play and Amazon Appstore charts
But to what extent is this actually true? And does it have any impact on which games rise up the rankings?
Well, a cursory glance at the paid games charts for both platforms suggests not, since the rankings for Google Play and the Amazon Appstore have plenty in common.
Not so different, you and I
Take a look at the top 20 paid games on the Amazon Appstore and you'll find that nine of them are currently featured in Google Play's top 20, too.
That means that 45 percent of the top 20 chart is the same across both platforms.

If we expand our gaze to the top 50 charts, though, there are fewer titles in common. A total of 15 games can be found in the top 50 paid games list for both platforms, but this still represents an overlap of 30 percent.
And it's overwhelmingly the big names that appear in the rankings for both platforms, suggesting that the Amazon Appstore and Google Play aren't so different after all for the likes of Rovio, EA and Disney.
Giving it away
An examination of the free games charts tells a subtly different story. Only seven games in the Amazon Appstore's top 20 free games chart are also ranked on Google Play's equivalent top 20.
However, the Amazon Appstore's top 50 free games chart shares plenty of titles with Google's store. A total of 19 different games crop up in both the Amazon Appstore top 50 and the Google Play top 50.

In other words, 38 percent of the top ranked games on both platforms are the same.
It's the little things
Rather than dwelling on the titles that have achieved cross-platform success such as Jetpack Joyride, Angry Birds and Where's My Water it's more interesting to note the games that have only cropped up in one store's rankings.
G5 Entertainment's hidden-object games, for instance, are nowhere to be found on the Google Play top 500 paid or free charts.
However, there are currently four different G5 games in the Amazon Appstore's top 100 paid games chart alone. What's more, G5's offerings sit alongside plenty of similarly packaged hidden object-games in the Amazon rankings.
It's little trends like these that suggest that the Amazon Appstore really is a different ecosystem, albeit ones with extremely close ties to Google Play. Although there's significant overlap, there's clearly a subtly different user profile for the average Amazon's Appstore shopper.

It's likely a consequence of the fact that most Amazon Appstore users own a device from a single product range the Kindle. Amazon's low-price content consumption tablet has attracted new users, and these users are seemingly content with much of the same content they'd find on Google Play.
They're just particularly fond of hidden-object games right now, too.
