"48-hour" rule 

The "48-hour" Rule is the law that protects gamers who have recently purchased a new game from getting pulled away for matters that are not important. This list includes, but is not limited to chores, social functions, walking the dog, or other responsibilities.

To solve any debates, the 48-hour rule does begin upon loading the game up for the first time, not upon purchase.

This rule was created to provide safety to fellow gamers who were getting pulled away from their games in that initial learning phase and during important story plot. It was noted that parents and spouses would take advantage of these times and force the gamer into fulfilling chores or social functions just to get them away from the game. It was never researched on why these seemed to be key times that people would "need" the gamer to do chores, but it is thought that it may be due to revenge, jealousy, or just plain asshattery.

Thus the 48-hour rule was devised. This is to protect the gamer from any who wish to take away their new found treasure and ruin those integral first hours of gameplay. It also protects from negative emotions towards a violator of the 48-hour rule trying to force the gamer into breaking away from their new game.

NOTE: The 48-hour rule does NOT mean that the gamer has to play for 48 hours straight. Only that in those first 48 hours, a gamer can not be pulled away from their game for someone else's reasons.

Spouse: Hey, it's your day to do the dishes and take out the trash.

Gamer: "48-hour" rule, sorry.

I bought a new guitar, snuck it in the house and put it in the stand with the rest. Since Janie didn't notice for two weeks, the "48-hour" rule had lapsed so I could claim it had been there the whole time.
