I have been scavenging for articles like this. I believe, from reading quite a bit of information on some of these older games I played, from reviews, to user ratings, and from personal experience- that a lot of these games have aged so badly that they can no longer be considered functional. I recall having that itch in the back of my brain when I was younger when it came to Banjo Kazooie, Jet Force Gemini, and of course, Donkey Kong 64. The niggling feeling that it was tedious, but I was too young to understand how to formulate that feeling.
