I had my Sims 4 sim play a game called "The Sims Forever", and it was The Sims 1! This clip shows what is on their screen and the audio when they play it. I thought it was pretty cool. I know in The Sims 2 your sim can play The Sims 3, but this was quite nostalgic. Subscribe to me if you'd like, I upload videos at least a few times a week usually.
