I might have my students play a video game for a class. I was thinking of having them play an old game via an emulator. Is this illegal? It seems like it would be, but I recall some guy teaching a class on role playing games at some university. That guy must have taught via emulators.. I doubt he was able to secure original copies of the games he chose.
The main point of the exercise is for them to play a video game, and come back the next day and share their experience with learning how to play the game, the conventions within the game, and , if the game allows, portrayal of the characters based on gender (or race).
