in between work, wife, family, friends, dogs, chores, etc., my game playing time is also limited, though I can usually manage a few hours early saturday-sunday morning when the whole house is still asleep (i'm a early riser) although it is usually not that long before my dogs are staring at me to get up and take them for a walk.
I have pretty much drifted away from subsims, more because the market has moved on and the SH series is getting long in the tooth. Lately I have been playing il2 battle of stalingrad and Rise of Flight.
The only subsim I still play on and off is SH4. However, I recently picked up a campaign where I had left off 6+ months ago and am now all in again.
its like riding a bicyle, you dont forget..
