don't know if I would use the term "warm feeling inside", there are lots of things that make me enjoy my game and adore my sims, some are cute moments, some are funny for various reasons.
I love when my grumpy sims are grumpy during happy/friendly interactions/moments, or when my evil sims laugh at the most inappropriate moments, just as much as I love my soulmates finding each other and being sweet to each other on their own, friends and family hanging out and having a good time...
also what always gets me are the puppies, they are just so darn cute a shame you can't do much with them...also snow and family/friends/partners playin in it...I get a little warm in my heart when I think of winter.
