I can relate to the OP, I have a small baby that takes a lot of my time, and I don't want to miss out on hanging out with him all I can while he's small.
This guy :
He's currently LVL2, haha.
Anyway, I've actually had a weird history of gaming.
0-6yo : rarely gamed, but did start typing games in basic (copying them into our Atari 800 from Byte/Compute/etc). Was fun and frustrating due to the terrible keyboard and lack of disc drive to save the games I typed. The good games were always many many pages of code, and if you didn't type it all perfectly, things were broken or strange. I did learn a lot about basic programming from this though, to the point of altering the content to suit my tastes (names of things, colors, even sounds after a while).
7-12yo : Did a lot more gaming, brother got SMS, I got a Gameboy but played a lot of NES at friend's houses. Won NWC, got a NES finally.
13-15yo : 16-bit! Played the poop out of Genesis/SNES/Amiga/ST stuff.
16-22yo : Moved, went into major rage mode of my life, rarely played games. Tons of anadrol/testred, I was not a really nice person during this era.
23-25yo : Played more games, but not more than 1-2hr a week really. Though once in a while I'd get the chance to spend a few hours with a great title.
26-30yo : Almost nothing.
31-36yo (current) : Played very little, but did start collecting old stuff, got lassoed back into classic competitive gaming for a brief period (I promptly re-retired). Played BF3 an hour or two a night for a while when waiting for my son to be born. Now I play maybe 30 minutes to an hour a week. On the rare occasion that I get the house to myself for a bit, I'll either sleep, catch up on work, or get in some BF3 action for a few rounds.
I do wish I had more time, there are some great games out there, and I know I missed a ton of greats over the years, but maybe when my son gets older I'll spend some more time. The lady of the house plays some Wii and the 3ds I got her while she was in the hospital for 6 months waiting on our little one. And she plays a lot of Hidden object games (stay at home mom) while he naps during the days.
