We want to download other programs, such as some games from the Google Play store or Steam. We thought we had managed to download and install a game from Google Play, but can’t find it on the Piper. I am really hoping this computer can be more of a true computer and not just a Minecraft machine.
Have you exited to the desktop and seen what is preloaded on teh raspberry Pi (the heart of Piper)? You can load Scratch, Wolfram Alpha, Sonic to name a few. You can even get another SD card and turn it into a media server.
Go take a look at the > Raspberry Pi Foundation’s webside to see all the things you can do
Another cool use: turning it into a retro console emulator: http://lifehacker.com/how-to-turn-your-raspberry-pi-into-a-retro-game-console-498561192
