You can learn and understand history various ways such as learning in a university, reading books, being taught by someone with a background in history, watching TV, browsing the internet, or, in my case, (and my question) from games.
How can I be sure that the source that I am learning history from is the correct source? Maybe (or most of the time) this source is hiding information or neglecting it. I didn't study history at a university, but at first TV, such as National Geographic, and later games were my sources of collecting information. When I was a kid, I played a game called Age of Empires. It was the first game that gave me some info about history, such as the different eras and some knowledge about civilizations. Other games, like Call of Duty or other shooter games, talk about history as well. However, there is a game called Civilisation that is really really into history and goes into various detailed things about every civilization. However, I discovered that games in general gives you specific information in order to achieve the game purpose. For example, Call of Duty in some series points out how the Nazis were bad and Hitler should be killed. In Civilization, there is information abut civilizations that are missing and there are questions about why they specified such people.
My question: the source we are collecting information from most of the time is hiding information or showing incorrect info. Especially to an amateur like me who likes history, how can we avoid such things?
