Today's Gaming industry as evolved well into a vast field : Indie developers, commercial organisations, hobbyists and more.
It's come a long way from being a way to while the time away into a whole entertainment experience.
As this evolution keeps progressing more and ore people begin to play and develop games. It's naturally proven that games can influence the mindset of a gamer, many may say gaming makes people violent or narcissistic but in truth a game is a means to influence people into a state of mind to relate to a character they control. The responsibility of moulding society partially falls on developers as well.
A game that is developed (be it of any genre) allows the gamer to experience the character's emotions (be it a game character or an unseen force like in strategy or puzzles).It is important while we develop to utilise this powerful tool to improve people's lives. I do not mean to say that violent games are evil, rather games need to inspire people to believe in something. A warrior fights for a cause that he sees as just (Freedom/Country/Money).It's games that entice your mind into a gambling loop that are not helpful to people.
So when you begin conceptualising a game, please consider the effect you can make on the player and take maximum advantage of it to make a better society.
Games are a means to have fun lets not make it a routine but rather an experience.
