I'm a Civilization fans since I bought my very first PC when I was studying in highschool. It was the Civilization II that make me crazy about computer games. After Civilization II, I played few other series of Civilization, but time always not allow me to finish it.
This time Humble Bundle bring the Sid Meier series to everyone. Basically you just need to pay USD1 and you can have 5 Sid Meier's games, yes it is all genuine games. You may don't know who is Humble Bundle, you can read it here. Basically, it is a type of charity funding site. When you buy those games, part of the fees will be donated to the charity.
So, if you like Civilization games, or you want to try it, and at the same time you want to do some charity donation, you may go here to buy the title. I bought mine although I really don't know when I can have some spare time to play these games. Anyway, just few USD and I can have my favorite games and at the same time do some charity.
