Last week, I had a lot to say on respect. I thought I would have enough content to warrant each virtue its own post. I don't.
Respect
Gamers come from all sorts of backgrounds and gene pools. They are all human and deserve to be treated as such. More over, they should be treated as a comrade in arms, regardless of heritage, upbringing, or lifestyle. Games are for everyone.
Treat others with the respect they deserve, and demand the respect you deserve. We are all here to play. Give your respect freely until you have reason to revoke it. Welcome new players with respect, and our community will flourish.
Loyalty
As a gamer, you belong to a fellowship of players. Do not betray this comraderie, and, more importantly, do not betray the game creators that make this community possible. They should have your respect and admiration for their great sacrifices made on a daily basis. Be loyal to them.
Stand up and defend them for the work they do, even if you disagree with their decisions. Don't like the sorceress design in Dragon's Crown? Good, have your opinion. Don't like that your favorite weapon in Call of Duty will have its damage decreased by a hardly perceivable amount in the next patch? Feel free to get sad, even mad, but understand that game design at such a minute scale is intensive work that has been thoroughly playtested. Even when the publisher mandates a feature into a game, stand with the developer. They will deliver the best game possible under their constraints. If a feature prevents you from enjoying or purchasing a game, write to your developer to voice your opinion in a calm and respectful manner.
Do not pirate any game under any circumstance (see Extra Credits for the one and only exception). Getting laid off because your studio doesn't make enough money is devastating, and studio closures scatter amazing talent.
Finally, do not ever threaten any gamer or game developer in any capacity. I shouldn't have to even say this, but some people are just less than human. Deny these monsters the rank of gamer - they are not worthy.
Honor
Do not game the system. Be it the integer overflow in Diablo III, the dance-to-disengage from SWTOR, or EA's new return policy for digital games, do not take advatage of games, developers, or publishers.
Do not cheat in multiplayer, and obey house rules (e.g. no Oddjob in Goldeneye, no overshield in Halo, no "power overwhelming" in Starcraft). If the developer left cheats for you, enjoy them honorably - in single player or when cheats have been declared fair game. Play fair.
Do not rage against quit. Admit defeat in the time honored tradition of "gg" - "Good Game." End all matches this way, regardless of the victor. Lose with grace.
Honesty
Be true to yourself. Whether you like or dislike something, do not deny your feelings. Be prepared to explain your opinion in a well-formed response.
Do not "go easy" on a less skilled player without their request. To do so is disrespectful. Respectfully offer a handicap if you feel it is warranted.
Benevolence
Be kind. The world has a very poor opinion of gamers. If they saw more good works, such as Child's Play, maybe our public image would improve.
Be kind to new players. Welcome them to our community. Offer to help when it is timely, and offer constructive criticism if they ask. Be helpful, but do not mandatr their actions. Let them choose how they want to play the game.
Courage
Have the courage to stand up to adversity. Stand up for games, gamers, and developers. Do not suffer disrespect of yourself or others. Stand tall and proudly proclaim you are a gamer.
Have the courage to be honest, to do what's right. Have the courage to wait until you can buy the game instead of pirating it. Have the courage to hold your angered toung.
Finally, have the courage to admit your short-comings. Have the courage to improve.
Rectitude
Be righteous: Do what is right, always and without exception. Act respectfully, even when you're in a bad mood and losing the match because a new player on your team doesn't know what they're doing. Be honest, even when your opinion is not the popular one. Do what's right, now matter the circumstances.
