Boomer today is used for anything that’s old, and I wouldn’t be surprised if you get Gen Xers that get called boomers. Since boomer shooters are a homage to old shooters, we call them boomer shooter. The ultimate problem is that it’s just catchy, so unless you find a more catchy term, you’re shit outta luck.
Gabe Newell’s quote from 13 years ago will never not be relevant in such discussions:
Spotify, Netflix (in it’s earlier days) have shown that time and time again. People love convenience. We are ultimately lazy animals. I think if you created a streaming service tailored to really old, obscure shit and you gave it a reasonable price, people would buy it.
