CivIV might be the best in the series when you consider the whole package, especially after the excellent "Beyond the Sword" expansion. However, one thing really bothered (and still bothers) me: stacking! And the developers answered my prayers in CivV which makes it really hard for me to go back to CivIV! I believe stacking makes the CivIV wars so boring and so "unstrategic", it has been really hard for me to go back from CivV (and now CivVI) However, I still miss some aspects of CivIV: best use of religion, best balance of micromanagement/automating them, corporations (although it needed some more balance testing imo), mods, wonder videos and Leonard Nimoy's excellent narration!! Also, worth mentioning is the "Colonization" expansion included in this package. Those who know the 90s original game, should definitely try it. This is as good as it gets!
