My oldest (12) loves to create games in Scratch! He still clings to Scratch (and has his own Ubuntu too), but I want him to look at:
* S2js http://www.s2js.com/
* Snap http://byob.berkeley.edu/
* https://www.scriptacademy.net/ (also js)
* https://love2d.org/ 2D, Lua
* maybe https://www.renpy.org/

Leveraging his love of Minecraft:
* https://github.com/walterhiggins/ScriptCraft got some interest
* https://code.org/minecraft
* http://edublocks.org/ he didn't like the Pi slowness compared to his desktop
