I'm looking for an online game with a persistent world where you are allowed to code (and add) your own 'players' (it can be in any language / script).

A sort of RTS but for bots.

Does that even exist?

I don't know if this is going to be useful at all, but just in case. RealTimeBattle is a programming game in which you program robots that fight each other. – Dan Nov 28 '11 at 14:38
How is this game dev related? – Tetrad Nov 28 '11 at 15:09
@Tetrad : 'Programming a bot for a game' seemed quite game programming related to me. – Valmond Nov 28 '11 at 15:29
@Dan : thanks I'll check that one out (even if it isn't in a persistent world). – Valmond Nov 28 '11 at 15:32
@Valmond "programming a game" and "a game that involves programming" are somewhat different topics, but I'm not going to push the issue. – Tetrad Nov 29 '11 at 6:23

Yes, there is. It's called Robocode, and you basically program your own bot in Java, and fight with other people. You can battle against other AI bots, or play multiplayer over the Internet.

Here's the link to their homepage:

I was about to say something like 'I have tried RoboCode a long time ago but it isn't persistent'. Thanks though & +1 – Valmond Nov 28 '11 at 15:30

Since recently Heroes of Newerth has the ability to program bots:

There is also the Ai Sandbox, which is by the creators of AiGameDev ( Here is the link:

It isn't actually released yet though, but I for one am quite excited about it :)

Nice! +1 (but still no persistence) – Valmond Dec 1 '11 at 14:59

Carnage Heart on the Playstation 1 was a similar example:

Not online nor in a persistent world, but it did have an interesting flowchart-based programming model and was quite impressive for it's time.
