Personally, I take two nights a week. One to play games and the other to work on them. Projects are slow coming, but they do get done. With a 2 and 3 year old if I can eek out anything more than that, it's gravy...
Things slowed up on the arcade front for the first six months after each of the kids were born. When your youngest starts sleeping through the night, things will open up for your dude time.
