For Gamers: "Using the internet for EVERY game you buy is the quickest way to end all fun and intrigue to be had with said game."
"If you get angry/sad or otherwise stop having fun, stop playing, take a break, and tell yourself 'its just a game,' everyone will thing higher of you for it, those who do not arn't worth your time." <-- also good for generating a Zen-style, gaming attitude.
"If you 'single-player' an MMO by yourself and raid without any sort of vocal communication or interaction beyond text that would be considered comraderie, then you must accept that you've become a basement-troll."
and finally, "Inventing your own creed for being a Gamer is cool, getting a tattoo of it across your chest/knuckles/back might not be. Especially in your late 60s and on."
For Gamer parents (kid <18 yrs old): There are plenty of awesome, intriguing game titles to play that are appropriate WITHOUT being a BS playstation flower game, or otherwise wimpy enough to get your kid beaten up by his other gamer friends.
For Gamer parents (kid >=18 yrs old): If you don't agree with the game your 'kid' wants, make him/her get a job to buy it instead, then do not complain when they play deep into the night, unless, they jack the volume up and wake you.
Captcha: "spread the net" Will do, captcha. Will do.
Edit: Sorry, I made multiple points, but you have to admit, most of them are valid...
