ET definitely had a reputation back in the day. I'm not saying I personally think it is as bad as most people say it is, but I distinctly remember neighborhood kids baggin' on the game in the 80's. I ended up with like 4 copies of it somehow, almost as if it was quietly reproducing in my game drawer. I think it must have been because kids would come over with their game collections and leave ET behind (how convenient). Maybe it wasn't intentional, but I couldn't help but notice nobody ever "accidentally" left copies of Enduro or Stargate in between my couch cushions.
I'll never forget this one time I saw an Atari with games at a yard sale near my friend's house back when the system was still alive and well on the market. I remember seeing games like Seaquest and Atlantis selling for around $10 a pop, but the pristine ET cart sitting in the lot had a price tag of $0.25. This has stuck with me because I was just floored at the idea of being able to buy a game for a quarter; too bad I already had 4 copies of it.
As for the Nerd, I enjoy his stuff, mostly because it's one of the rare retro gaming YouTube channels with any sort of production value. There's nothing more tedious than sitting through a video of a guy filming himself on a webcam in an echoey room going "uhhhhh.... So..... Ahhh....yeah....uhhhhh....so that's my video....uhhhh....thanks for watching" while the words "please subscribe" flash on the screen in big ugly letters on a magenta background, and fade out in a cheesy Windows Movie Maker animation.
