Thank you all for the support!
I am happy to run it, as long as I have someone like Praetor to help me out with the codes and riddles. I know I may have said that we shouldn't get the riddles and stuff off of the internet, but thinking of new codes and riddles would be incredibly tedious and time-consuming. Therefore, I suggest that we take some of our codes from the internet, and maybe change them around slightly. We should probably have regular updates (maybe every few days or a week) announcing the nations who have made it into the region.
Now, I must admit, I am not a very good riddler, so that is why I need some extra helpers around for it. Let's consider this a joint project between the Ministry of Gameside Affairs and the Ministry of Culture and Entertainment. I think this would bring a lot of nations together, and form bonds we haven't really seen on the game before. And Praetor, I agree with your suggestion. After the first five nations have successfully entered the region, we will check them to see if they are safe and not malicious. Then we will give regular shoutouts to those who crack the code afterwards and send us the answer privately.
One thing we must discuss before we start properly working on the idea is what the nations are going to do once they get into the region. It may be fun trying to get INTO the region, but what is there to do for them once they've made it? Perhaps we could hold regular code cracking competitions and activities, where we could organise some deciphering battles and riddle quizzes. I strongly advise that we set up a solid and logical plan before making any moves. We would have to have everything ready before launching a project like this. Post your own takes on this idea below.
