Nintendo is definitely not the only one that makes amazing OST's. Uematsu is one of my favorite composers, his themes are always so intricate and interesting. This makes Square Enix have some of the absolute best OST's I've ever heard.
The one posted in this thread, Sunleth Waterscape from FFXIII, is extremely well done. (Edit: Also, Hamauzu is the one who composed much of FFXIII's music, or all of it. I don't really know...)
