Ok, I'm going to try and use an example from my experiences with renting old VHS movies, and hopefully, I'll make this explanation work somewhat:
Back in the good old days when you could visit kiosks for renting VHS movies, I did not really know much about movies. There were little to no trailers, not much talk about them in the newspapers, and definitely not on the internet because there weren't any, well, at least not for the public anyways. So how did I find out if the movie was good or not? Either I had buddies telling me how good it was and that would be a hit and miss. I also think we had some movie catalogs back then, you know the smaller thick ones, kind of similar to the telephone book? and also some info through text-TV. So you could read a little about movies from those. But, for the most, I would either read on the back of the VHS cover or I would just look at the front of the VHS cassette and see if I liked the picture. If the picture looked like it was waaaaay cheesy, like two dudes half-naked with swords in their hands grinning to the camera, I would have not rented it.
Soo, juuuust as with those old VHS cassettes, I will take a look at game magazines and forums now or hear what my friends say. The one big thing difference is that instead of looking at the movie picture or reading the info back on a VHS cover, I now watch snippets of gameplay to see if it's any interesting. Just as with the VHS pictures, I will most of the time be able to differentiate between what is good and shait for me. Phew, this was a handful! 😅 😅
