Probably my favorite type of game, I've played dozens of them but I'm always looking for something good I might have missed. My personal favorite for the past few years has definitely been Farthest Frontier but theres been a ton of good ones. And if anyone else is looking for recommendations let me what you like and I probably know something that fits.
I've played so much Tropico. Great series but the last one seemed like merely a rehash of five. Game play and the jokes were pretty much the same.
