I'm a 6ish hour a week guy now. Summer really drops my playtime. I love being outdoors or working on the house as much as gaming. Winters are definitely 15-20 hours a week though. Life then becomes sleep, eat, work, move snow, play EQ, rinse, repeat.
Kids are easiest when they are babies...no playing necessary, they just sit there (so long as you have one of them quiet ones! i got lucky
). Never had more playtime than when i had a kid. Took 2 weeks off work, held the kid occasionally, played eq while holding the kid. Now that shes 2, she wants to color, or go outside, or read curious george and the missing puppy.
