There are times when gameplay and pure joy can make you forgive any technical or artistic glitches. Civ2 is the best example of this. I cant count all the sleepless nights in college spent in playing Civ2. It was pretty much the second RTS game i fell in love with after Colonization, and I'm in love with it to this day.
Civ2 has a remarkable longevity of gameplay. You can replay this title countless times with different civilizations, and weapons. A truly fantastic experience that all my other RTS games will be measured by.
