Roblox has kind of gone through a number of iterations. There was a time where it was really deep by default (and not much point and click) and knowing a good amount of Lua was useful. It has been around since 2005-2006, long before the iPad existed. I was .. 10 at time of release, it was really fun :).
I (and a lot of my friends) got their first real start with programming using Roblox back in 2006. Most of us now work professionally in software or security, directly as a result of our experience with making games in Roblox, or hacking the game.
Writing exploits for Roblox gave me experience with everything from binary analysis to web security and cryptography.
I've heard similar stories from other people for games like Runescape or Minecraft. It's really astounding to me the ways in which a dedicated enough teenager can take advantage of games to turn them into something really educational.
Also, my handle in Roblox was Aeacus! Hit me up if we ever played together :) I'm sure there's a ton of overlap between HN and the smallish Roblox scripting community of 2006.
