The vast majority of your nation's people will be completely inconsequential. What you'll be putting in a post are decisions made by the leadership, negotiations carried out, etc. There's a lot of creating characters on the fly without filling a form, and it takes a lot of thought to be able to think on a national level. However, I find that the challenge is greatly welcome.

And I actually haven't played Other M. I watched all the cutscenes and don't like the story, but I heard the gameplay saved it from being totally horrid. I've heard the gameplay is amazing, and it certainly looks amazing from what I've seen. But my favorite Metroids will always, and I mean always, be the Prime Trilogy. And since Metroid is my favorite franchise, that makes my three favorite games of all time the Prime Trilogy, with my favorite game of all time being the second one, ironically, especially considering that it's the least popular Prime game.
