By the time Firaxis had pumped out Civ 4's second expansion, Beyond the Sword, the legendary history-builder was as tight, wide-ranging and complex as it had ever been. No small world wonder, then, that when a trendy, slim-line Civilization 5 scooted in on a pair of wheelies and did a 'Fonzie-point' with thumb and forefinger towards newer players some Civ acolytes elected to stay behind.
For many, systems like Religion and Espionage had become part of the bedrock, as integral to Civ as the desire to crush those bastard Romans. It was seemingly impossible for some to go without the complexity, hexagons or no. With Gods and Kings, then, Firaxis aims to let Civ 5 emit enough cultural significance to retake the allegiance of the players who currently sit beyond its borders.
First on the agenda, then, is the reintroduction of religion. Could this be the point that we can answer the enduring question of 'Which religion is best?' without resorting to the 'Well, my one, obviously' default?
