The original Starcraft will always hold a special place in my heart, I still can't think of any single game I played more than SC. The sequel was good but it just never felt the same, it became far too competitive too fast and because of that I can't get into it, it may have a huge community but it will never be the same as those days of dial up Battle.net with clans and bots and all the crazy custom use map settings games that seemed to never end, sadly it did.
The only current game on the list I can say I have truly enjoyed playing is Civ 5, but that in itself is a whole lot different from the Starcraft formula, mainly because it's turned based and not real time. I am glad AoE made the list at least, another great RTS game I played a whole lot of in high school. Company of Heros is also a good title on the list, but one I never found myself wanting to go back to, I have the box for it somewhere with the discs, but am not about to go looking for it.
Lastly, what the Gif for Crusader Kings II? Do I even want to know what that has to do with the game?
