Civilization V was quite the departure in 2010 by moving from the square to the hexagonal grid on the map - but over the years the many expansions and DLC added so many other worthwhile changes and improvements, that now only this Complete Edition is worth the purchase for the full experience! This game is still worth it, despite CIV6 etc. to have been out yet - get it when its on a decent price (>20), and you will not regret it!
