I actually don't know any great coders that learned to code through these kinds of games. They might move the programming-is-interesting gradient, but I don't think the hard part about learning to code is the text.
The hard part about coding is the problems that aren't in the code. Doing research, setting up environments, understanding platforms, dealing with crashes, dealing with crappy tools, debugging, understanding other people's code. None of this is taught by isolated sandbox games like this. Sandbox games might teach some very useful analytical skills, but it's pretty far from coding.
The only thing you really need to get kids coding is to give them the tools needed to do interesting naughty things. Many of the programmers I know learned to code at an early age by hacking games to cheat against their friends. Reading text was never, ever a problem, but the disillusionment of finding out that coding doesn't involve pretty foolproof user interfaces might have been.
