Short Information.
I recognized that the new humble bundle includes some pretty nice stuff (in my opinion).
You get Civ 3, 4 and some airplane games if you pay 1$ or more and if you pay more than the average, then you get Civ 5 either, together with the gods and kings DLC.
So i think its worth it, but have a look by youself, anyway I can definitely recommend Civ 4 and 5 cause I played both of them and I still enjoy playing Civ 5.

Well thats it,
have a nice day.
