Having kids--passing on your genes--is the closest thing there is to immortality.
If you think you're worthy of it, you should definitely contribute to the next generation. Don't be so self-indulgent; there's bigger things in life than video games.
By that logic having kids is the ultimate act of ego and selfishness. I would say it's more selfish to bring kids into a shitty, overcrowded world just because you can't resist some biological imperative.
Have kids, great. However, not great unless you're going to give it your all.
The world is full of kids with shitty, selfish parents - fathers and sons...
