I mentioned that King of Dragon Pass is a big game. The original was something like 450 megabytes. (We fit both Mac and Windows on the same 650 MB CD by sharing files between the two file systems.) Now, that’s without any compression (I don’t think we had the option, though since it fit without compression we might have avoided it for speed). And the iOS version is for a smaller 480 x 320 pixel display, so the assets will be smaller. So the iOS version won’t be that large.
For development, I’ve exported all the scene artwork at the highest JPEG compression — also known as the worst quality JPEG compression. Since the game needs to be copied to a device for testing, smaller is definitely better. It will be easy to drop in higher quality art at the end (it takes the same amount of memory when decompressed, and reading from flash memory is quick, so I don’t expect any changes).
So right now, the game is about 57 MB. My worst case estimate is that it’ll jump up to about 150 MB with the right art. That’s pretty big, but the largest game I have is Monkey Island 2 at 398 MB. And the largest Apple will allow is 2 GB. You won’t be able to download King of Dragon Pass over the cellular network (the limit for that is 20 MB), but over WiFi or with iTunes on your computer it shouldn’t be that bad.
I just learned that the Android Market is raising its size cap, from 25 MB to 50 MB. I wasn’t planning an Android version for various other reasons, but I hadn’t realized that King of Dragon Pass could not be sold through the easiest channel. This puts any future Android version in serious doubt, I’m afraid. Maybe things will change next year.
