I quite like the idea of this RP Server. It is nice to see people want to write complicated game modes with the scripting system we wrote, that was one of the aims of it!
As Talidan said though, just having a storyline isn't going to be enough for you to pull this off. As far as I can tell, the resources you write for this will need to be well planned out before you even start writing them, or you'll end up rewriting things all the time and it'll end up a big mess! That being said, I haven't looked at your forum yet (I'm at work) so you may already have a lot of this underway already
I think I would like to try this out sometime, however I do not have a lot of time, and any spare time I do get usually goes into coding some MTA (which has been very little of late as I've been working 50+ hours a week!). But I will definately keep an eye on this as I think its a very interesting idea
If you do need any advice on writing any of your resources though, I would be happy to answer any technical questions you might have.
Good luck
