The actual BAFTA article with the full list starts off by mentioning most influential game on popular culture, which is going to be different regionally. Shenmue may have been the most influential in Japan or the UK, but it sure didn’t have the effect on pop culture in the US that Mario, Zelda, or Minecraft has had, not even close.
Yes. I use a FireFox extension called ViolentMonkey that allows you to install scripts.
There is a script called Simple YouTube Age Restriction Bypass: https://github.com/zerodytrash/Simple-YouTube-Age-Restriction-Bypass?tab=readme-ov-file
Install the script in Violent Monkey and you should be all set to watch age restricted videos in Firefox without signing in.
