I can't be the only one with thoughts like this, right?
I do not think people understand what your thoughts actually are. I read the other thread and this, and I do not understand.
It is unclear if you talk about a hypthetical game you would create, or about a hypothetical game, you want to play. It's also unclear if you talk about one game or about several games.
Experiencing another era of a topic is certainly something people think about. Imagine a mathematician wanting to discuss things with the ancient philosophers that invented certain concepts. Or a music band imagining how it would have been to release their songs at the hight of popularity of their particular style.
If you want to make a game you certainly have it harder and easier, as you would have 20 years ago. It's easier because of all the modern tools like game engines and all the experience of other people you can rely on. And it is harder, because video games are a lot more popular and easier to create, so you face the danger of obscurity. Also people expect more of games than they did 20 years ago. What then would be a game, might now be considered a mini game.
