I get up about 4:30 in the morning most days anyway. This goes back to growing up on a farm: at some point as an adolescent I started getting up at O-dark-thirty with my dad. We wouldn't say much. He'd sip coffee and read the morning paper, I'd eat some cereal and do my homework. Nowadays it gives me a couple hours before the rest of the family is up for quiet reading, knocking about the internet and simple utterly selfish solitude. A vast number of the posts on this blog were drafted out before 6 in the morning.
Along with already being up anyway, the practical advantages are twofold on my end. I can borrow my wife's kickass MacBook without inconveniencing her and I don't have to worry about my daughter's needs, since she's asleep.
But I like the suggestion that I'm selflessly sacrificing my morning to run games for folks thousands of miles away in the spirit of international gamer brotherhood. So if asked again maybe I'll go with that.
Anyhoo, don't expect any game to go longer than 2 hours. At 6:45 I need to be in the shower or the rest of my morning schedule will be shot to hell.
