This, to me, is the perfect stepping stone between the N64/PS1 era of 3d platformers and what they would become in the years following. Jak and Daxter was a huge technological evolution from the Crash Bandicoot formular for Naughty Dog, with vast, open, challenging world areas, an entertaining plot that didn't talk too down to it's audience, and a killer soundtrack - and all with next to no loading times whatsoever. This was my first 100% completed game as a kid and is still stunning to this day.
