Sounds pretty heavily like an attack, but some people indeed work hard on their videos. I think Audio is really the key. At least from what I've heard.
Super Mario World. I started with the SNES. It may have also been Teenage Mutant Ninja Turtles for the NES, which I would have played at a friend's house.
...best ending... best ending... The Last of Us. Some people weren't happy with it, but I thought it absolutely nailed it. Bioshock had a fantastic ending as well.
