I have played Civilization IV (and expansions like Warlords and Beyond the Sword) many many times. I seriously believe Turn-based games like CivIVrequires very much strategy like RTS games because of genius Sid Meier. He made slow-paced and borrring turn-based genre an exciting and one of the most selling PC games in the history with his Civilization series.

Recently I bought Civilization IV complete edition, which comes with all Civ4 games and Colonization standalone expansion. I didn't play Colonization before but after playing it - I must say his magic is still growing. It is indeed a great expansion.

I can't stop playing it ... Hats off to you Sid Meier for this great franchise.
