One of the things I'm loving about Westworld most is the video game comparison, both with how interactions with certain Hosts activate particular storylines and also the analogy between what some of the guests do to the Hosts and what people do when playing games like GTA without caring because none of it's real. I think taking a futuristic concept and grounding it in ideas that are recognisable and very current today (albeit in different form) was a really good idea.
...when you think as well of the original movie and no thought back in the day then could have been of the possibility of computer interactive characters and stories becoming a reality...(there probably hadn't even been colour in movies for that long....)...
Spoiler:
...also the reference to Teddy having died thousands of times...yep, he's Kenny.....
