I promised something about PSO2es earlier, and here it is.
SEGA just announced today that the app has been downloaded 300,000 times since its launch, iOS and Android combined.
As a matter of fact, PSO2es had a "strange" release policy, with the Android version being released much earlier than the iOS one. In fact, it was out on Google Play on April 1st, while iOS users had to wait till May 14th.
Now, let's look at how downloads went from launch till now.
First, the version that came out earlier, Google Play.
It had a very low-profile initial release; then, it started gaining ground with the new versions being release, peaking at 35th on April, 10th.
After that, it went down continuously, except for a return almost in top 300 in the second half of May.
Now, what's the result of such a run, in terms of downloads? Google Play actually show amount of downloads

In this case, it's between 100,000 and 500,000
Now, let's consider just the lower limit. Considering current achievement, this means that the iOS version has been downloaded less than 200,000 times since its launch on May 14th. So, less than 200,000 downloads in two weeks.
This is how the app went on iOS Most Downloaded chart: high initial placements, then a gradual progression to the bottom of top 100 (reach on May 20th), then out of top 200 (May 25th). On May 29th, all of a sudden, it's first again. Then, starts dropping and now, it's well outside of top 400.
This means that a game that started in high positions at the beginning, stayed in top 100 for 1 week, through a gradual drop, then stayed in top 200 for 5 days, it went back to being first and near the top for 1 day and then going deep down again reaches less than 200,000 downloads in two weeks.
Feel free to correct me if anything of this is wrong.
