One of my colleagues has had me guest lecture in her History of Video Games class about Atari and that era of games, but mostly I focused on Atari (with lots of memorabilia), and she had me come back for a second day to let the students actually play some of the games. She requested certain titles - Adventure, Space Invaders, River Raid, Yars' Revenge, Pitfall II, Ms. Pacman, Donkey Kong, and ET - that the book she's having them read specifically mentions, and I rounded it out with a bunch of other common (Combat, Frogger) and very rare titles (Boing!, Glib), but of all the ones I brought the most popular games were Outlaw, Kool-Aid Man, and Raiders of the Lost Ark. Regarding the latter, the students were amazed at the complexity of the game given the time when it was made. It was interesting to see them sit down and attempt to play a game that they thought would be easy (like Vanguard) and realize there was more going on than they expected and that they actually had to read an instruction manual. It was really interesting to see them get super competitive over Outlaw.
