If you are wanting to script a game yourself, then you need to be a pretty advanced scripter before even starting. Even fairly basic games will require at least a decent understanding of mIRC scripting. And I'm not sure anyone wants to write an entire game for you.
If you really wanted, you could post the basic idea and see if someone wanted to help with it. Something similar may even have been done before.
** Note that this should be in the scripting forum. The developer forum is for addons to mIRC and such, rather than just regular scripting projects.
