Ever postponed learning Lua because you'd rather be playing a game?
Then you might want try this (read a review here)
I'm having fun while brushing up on the basics

Got anything like this for C or Java?

Spring AI, starcraft AI, robocode, etc.
Depending on the type of problem, there are many other games which you can make AIs for.

Of course one can write an AI for a lot of things,
but the point of this game (and I might not have made that as clear as I intended) is that it is very much a tutorial on basic Lua.

It teaches you step by step how to make your train do what you want (while considering you might never have programmed in any language before.)

I haven't found any alternatives. But for C or Java this site might be interesting.

My answer stands. Robocode is especially easy to use when learning programming.
