Game to lose myself in, that I can think back and say "man I'm glad I played that"

I used to be grateful for every single game I could lay my hands on. These days I've gotten into the habit of only playing games that are easy to get into, shooters and action mostly. But now I'm finding myself thinking back on the days where a single game created lots of good memories, nostalgia. Some examples would be Final Fantasy X, Kingdom Hearts and Baldurs Gate (and even Myst). I played a lot of Pokemon and strategy games when I was younger, but thinking back on those doesn't do anything for me. I need music, a virtual and beautiful world to lose myself in. That I in the future wont see as a waste of time, but a fond memory that creates nostalgia. I'm sure a lot of you can relate.

I guess I'm looking for modern story driven games with good (and varied?) music. For PC or NDS/3DS, maybe even PS2. Any suggestions?
