I have had a lot of people ask "Why have you not released Survivor Z for Android Devices?" Well, the best way to answer that is with a question; "What kind of Android Device do you have?"
And no matter what answer they provide, they have answered the question of why we don't have an Android build, or at least a big part of it.
The reason is really simple and two fold, and believe it or not, not about which platform is "superior"
for a developer, it comes down to this:
1. Android devices are not identified as a single group or even several groups. They are literally thousands of different devices, all with their own unique processor families, screen sizes, resolutions, and even operating system versions. And no matter how cool you are, you can go broke trying to release a game that works on even half of them. This is called "Device Fragmentation" in the business, and while a free market is beautiful, standardization favors the developer.
2. The other reason is mostly cultural, and I say this at the risk of sounding judgmental and condescending, but I am basing my statements on purely empirical evidence that completely supports this hypothesis:
Android users do not prefer to buy apps, they prefer to get them for free. I don't have a problem with that, the Operating system is free, the devices are much cheaper than the Apple Stuff, and the Google Play market is practically open anything goes compared to the rather regimented Apple App Store, believe me, I get it. But you must also believe that a developer who loves (with every fiber of our being) loves making games that we want to do this and nothing else, but we can't quit our day jobs if we don't make money. And the Google Play market simply doesn't earn you anywhere near the money that Apps in the App Store can make, and thats just the way it is.
No matter how you slice it Fruit Ninjas, the Android market is a comparatively weak market to make money in. Google has made it easy to upload any app that you make, and that has brought a lot of apps into the market, but by doing so, they have driven down quality, as well as customer expectations, and made it increasingly difficult for a small developer to crack that market, and even if they do, device fragmentation is waiting on the other side of the door to hit them right between the eyes.
We are trying to include an Android Version, but for us to spend that time and money it has to make sense. And I hope it does soon. In the end, the two options that really look the most promising are just targeting a few of the larger device families, such as the Samsung Galaxy, the Kindle Fire and the Nook HD. (And everyone who doesn't have one of those just felt a pang in their heart) - which only reinforces the point.
Unfortunately, I can't say definitely if that will happen, and I certainly can't speculate as to when. I would say that if we did it at all, it would make the most sense to do it in the Spring, while we still have some of our launch momentum.
