Unhealthy pressure

Shalkis and I had a discussion that touched on some of this before. But I've noticed something happening in my own guild that made me want to talk about it further.

If you have a situation that through positive or negative reinforcement you are pushed to play more or longer than you should, is it Blizzard's fault for putting those types of situations in the game? In the case of raiding, is it the guilds' fault for not fostering a healthier environment? Is it the player's fault for not restricting themselves?

I hope I correctly paraphrase Shalkis when I say he thinks its up to the player to decide how much time he or she will play. And I agree. No one puts a Wolfslayer Sniper Rifle to anyone's head and says play more!

When you notice people obviously aren't spending time with their own families, or the reason why they play so much is that they dropped out of school or are unemployed, shouldn't the opposite be reinforced? Or do you just assume everyone is an adult and can handle their lives as they see fit?

I guess I answered my own question. :/
