Just thought I would post up a game I have been playing for the past 3 months. If you are interested in politics, economics, and that sort of thing, you might wanna take a look at eRepublik. You join the game as a citizen of any country. As your character progresses (play for 4-5 mins a day, its a daily game) you get more abilities. Run newspapers, join the work force/military, get involved in politics, and such.
Right now, Thailand is still a small country (in the game) run mostly by foreigners, so all the functions are done in the English language. If you are interested in improving your reading and writing skills (especially in regards to professional topics), you should check it out. Here is a referral link. If you sign up through it, I can help keep track of your progress and answer any questions.
