Elbert has a collection of 15 games in the Windows Phone store, and hit 1 million downloads in January 2012. Despite the increased competition from the influx of thousands of other games he has maintained the same run rate, taking about 15 months to add the second million.
Little more than a year ago Elbert wrote that the gold rush for developers was over, and was looking to expand to Android and iOS. Since then he has ported his most popular game Impossible Shoota to Android, and it is of note that the game only managed to collect between 100 and 500 downloads in more than 3 months.
A possibly more chastened Elbert now writes:
Hopefully I learned a lot from my successes and failures in the Windows Phone Marketplace and will be able to translate it to other platforms in the near future. But just as a word of advice to everyone out there, not because you are popular on 1 platform means that it will translate to the same success on other platforms. There are just too many different variables that come into play that determines the success of games.
Expanding to other platform is of course a good idea, and we would love many Android and iOS developers to port their apps to Windows Phone, but moving from a less crowded market to the throng of the iOS or Android marketplace will always be challenging.
We hope developers who find success on Windows Phone will think of expanding their offerings on this platform, instead of being distracted by the greener grass on the other side.
