What gives you a "warm feeling" inside when playing?

I think the thing that makes me feel warmest is when older sims play with the toddlers. The sounds and their facial expressions are just so sweet, it's too much!

Recently though, I started listening to the sims 2 soundtrack on youtube and it gave me chills. I sunk thousands of hours into that game when I was younger and hearing the music just took me back to a simpler time in my life
