What are some of the deadly sins or actions that should never be done in the realm of gaming?
Things that are either extremely blasphemous or disrespectful or outright stupid that should be avoided for the sake of the gaming community?
Here are some of the bad things I see a lot
Eating Cheetos or Doritos then using someones controller without cleaning your hands leaving a layer of orange sticky greasy cheese slime on their paddle.
Putting a disc on the table face down instead of placing it back in its case allowing dust and scratches to appear on it.
Grabbing a disc by placing your thumbs on the bottom layer leaving thumb prints instead of lifting it by its hole.
Unplugging some ones console mid boss for the heck of it. Cruel pranks of that nature.
Not passing the controller after a death, taking 2 turns, or refusing to give a turn due to a technicality that the whole group did not agree upon.
Borrowing a game without returning it, borrowing a game and returning it in worst condition then received, borrowing a game and selling it/losing it.
Making fun of someone's favorite genre of game. Or ridiculing a game someone is playing constantly killing their mood or the fun of their favorite game.
Spoiling the end of a game someone is playing or telling them key parts of what will happen ruining the game for them.
Calling Link Zelda
