Some other discussions on the forum prompted me to think about what would be my top 5 favourite 4X games ever. While I am pretty sure about the two firsts, the 3 others are not as certain. There are a few other games I considered but I eventually settled with this.
This is a For Fun thread, do not feel obligated to explain your choices. Hopefully this might prompt some people to try some games they did not before, or discover some underdog gems. Although in my case my choices are quite mainstream.
1. Galactic Civilization II
2.Civilization IV
3.Alpha Centauri
4.Master of Magic
5.Colonization ( original Dos game )
