When I was little I had Barbie Beauty Boutique (or it was called something like that)
I'd play that shit for hours
Also I love Harvest Moon, and also Rune Factory (which if you haven't heard of it is Harvest Moon but you can fight monsters and shit, it's great). Ditto for Animal Crossing. I just like being able to relax and play something cute sometimes.
And I'm also one of the people who downloads mods for the Elder Scrolls and Fallout to make my girl look pretty. My first modding experience was when I was like 11, trying to make that shit work. Good memories.
It's also not quite girly, but I play Final Fantasy XIV, and I love being a little Lalafellan and making cute clothes for her to wear, and having cute little haircuts. Some armor, especially the war classes, make her look like a little slut toddler, but a lot of it is really cute looking.
