I remember back when my friends had their first children - twins, no less - and the effect it had on our gaming. It's tough, especially when they get old enough to walk and talk, but we managed to find a way. It wasn't quite the same as it was before, but you learn to be more economical with your prep time and how you run the game. So you have my sympathies. I think Dragon Age/AGE
is a good system for that, since it doesn't require nearly as much work as, say, Pathfinder.
I highly recommend playing the video games, too. The story in the first game, Origins, is fairly standard epic fantasy fare, and I know a lot of people weren't as crazy about Dragon Age II (I liked it, though), but where they all really shine is in their characters, and how they interact with you and with each other. And, of course, it helps to be able to see what everything looks like in the game world of Thedas.
If you feel like dropping the cash on them, I would also really recommend The World of Thedas Vol. 1 & 2
from Dark Horse as supplements. They're big hardbound books that detail the world. You're getting a lot of the same information about Thedas that you get in this single-volume edition of the RPG, but you also get a lot of great illustrations from Bioware, and as an art guy, I find that worth their weight. It's good for sparking GM inspiration as well as giving players something to look at when you describe a rain-soaked hilltop in Ferelden, the gaily-colored city streets of Val Royeaux, a woad-and-mud-stained Avvar warrior, and so on.
