I was instantly blown away by Metroid Prime. The controls (perfected later in Trilogy), worked fine for me thanks to the lock-on feature. The scanning, for the most part, was largely optional - I liked it because I was so caught up in the lore, but admittedly the scanning became more and more tedious with each sequel.
The atmosphere, level design and visuals were just astonishing to me. I remember an EGM editor saying, "It's like the best game from six years in the future fell through a time warp". I couldn't agree more.
