Has anyone written a script that allows game to run on its own (as on -ai) for a set length of time and then returns game to player? I could really do with something like this to enable me to get to later stages in play testing, but unfortunately am not sure I have time or ability to figure out scripting..

I'm assuming if it where possible it would only be a relatively short bit of script, so if anyone could give some guidance as to what it might look like.. I'd very much appreciate it.
