Favorite Game OST?

i'm trying to expand my horizons when it comes to game music, so i was wondering what everyones favorite ost is, for me i'm currently leaning towards Ar nosurge with xenoblade chronicles being a close second, here is just a sample of ar nosurge's ost:

It's way too hard to choose a favourite! I like the majority of tracks from SMT and its spinoffs (obviously), atelier music is really good too, and danganronpa's soundtrack is pretty great.... ahhhh I can't do it. ;__;

Unlicensed: No More Heroes
Licensed: Lollipop Chainsaw

I know these are quite common but I like Persona 3, Tales of Symphonia, Danganronpa, Atelier Dusk and Arland series, and I really liked Ragnarok Online music too...

I enjoyed .hack G.U's music i'm a sucker for opera-esque music or epica..? i suppose? if you pull it off right
