Ocarina of Time, it and Majora's Mask felt more solid and readable than virtually anything else on the N64. The dynamic lighting is a big part of how it all holds together so well, and it's still impressive how colour and shadow is used in some parts.
Rollercoaster Tycoon is also a thing of beauty, especially considering how crazy low the system requirements were, even back when it came out.
