As far as I understand, yes, this directory will always exist, although 
the exact location might vary. In Android terminology, /sdcard does 
*not* refer to an actual removable SD card, it refers to user-writable 
storage, which may or may not be a removable SD card depending on device 
implementation (usually not, as far as I have seen)

Ideally, I would like for people to be able to export their game as an 
android apk from the Distribute Games menu. They would have to install 
the Android SDK, and they would have to create their own signing key on 
google play and specify its location to the distribute game settings.

Then the Distribute menu could download a pre-built unsigned binary of 
the OHRRPGCE Game apk. it would add the game to it, add a user-specified 
icon (I want that for Windows and Mac too, but that is beside the point) 
and then sign it with their key, ready to upload to the play store.

Of course, We also need to be able to change the package name to 
something other than com.hamsterrepublic.ohrrpgce.game so I don't know 
how practical that will be to do with a pre-built binary.

For people who don't have their own domain name, we can provide a 
namespace like com.hamsterrepublic.ohrrpgce.games.gamename but I would 
also like to allow people to specify their own namespaces, so for your 
own game, tmc, you might choose to use 
com.castleparadox.tmc.foresttemple or maybe Mogri would want to use 
com.slimesalad.phantomtactics or Harlock might use 
org.crithit.spellshard
