New players tend to think very much in broad strategies and logical guidelines while good players tend to evaluate everything based on the actual game values and estimating what is actually good. new player: I have Morocco, my unique ability is gold and culture from caravans, i should take advantage of this, so lets send my caravan to the city state and not my expansion Good player: My UA bonus is only 3 gold and 1 culture, the culture is for sure negligible, and the early food in this expansion is more important than the gold. . new player: I should settle in this spot, that way all my resources are in range Good player: that spot has better tiles in the short term, even though i will not have as many resources in the end game, my early and midgame will be stronger from having my good tiles earlier, this bonus will even make my endgame economy stronger from the snowballing. . new player: I am byzantium, so i should logically go for the religious wonders, and go piety. Good player: When looking at the actual boni of the religion, its for sure not worth it to base your entire game plan around it, and invest so much in religion, losing out on better social policies. . New player: I should grow as much as possible in the early game! bigger cities are better cities, farm everything and work as much food as possible Good player: each early growth will give me 1-2 science per turn or so, and i have limited production tiles, so i wont have much production to gain, early growth only really means a bigger number, working alot of production is better to get my vital buildings/settlers/units out faster. When NC and university modifiers kick in, and civil service gives better value from farms, this makes growing better value, and that is the time to grow alot. I should mostly improve production early game. . New player: I have great production! i should focus alot on production! I have great growth! lets focus everything on food! I have great culture, lets build alot of culture things and become a culture powerhouse! I have alot of gold, i should build economic buildings so i can become an economic powerhouse! I am babylon! i should build the great library and become a science powerhouse! Good player: There are diminishing returns of all parameters especially culture and gold. Balancing all parameters is mostly better than focusing everything in one. . new player: I have X civ, therefore i should do Y otherwise X´s boni are wasted Good player. I have X civ, but Y is not worth it, Z is better even though X´s boni might be wasted. New players; Forming very long term plans, like getting all the tiles in range, leveling units too much, getting all the wonders before expanding, Dont understand the parameter of Opportunity cost Good players; prioritizing short term boni, since they know that getting things done fast is key.
