The NationStates game could be addictive, but fortunately it only gives you a maximum of two issues per country per day. Furthermore, the message board seems to be perennially broken, so there's no threat of sinking a whole lot of time into it. Five minutes per day is about all it needs.
Of course, it would be a completely different matter if players had the ability to trade or wage war...
You're permitted to create a maximum of four nations. So, I've decided to do an experiment: in my primary nation, I'll resolve the issues the way I think is best. In my second nation, I'll do the opposite of what I would normally do. In the third nation, I'll choose the most liberal option available, and in the fourth nation, I'll choose the most conservative. It'll be interesting to see how the nations develop over time.
(Speaking of being broken, what's up with the Teasmoke site? It seems like it runs out of disk space about five times a day, resulting in nothing but a Perl error message when I try to access it.)
