Oh my gosh, yes. The book had me reminiscing about the text-based adventures I used to enjoy, like Zork and Crystal Cave. I also used to play a bunch of the Sierra games - Leisure Suit Larry and the King's Quest series in particular. I was in high school when the original Atari game, Pong, came out, followed not too much later by Space Invader (spent a lot of quarters on that one!). And then PacMan. Ah, the memories...
I never got into the community aspect of gaming, although I can easily see the appeal of that. Certainly gaming offers more interaction than a lot of other forms of entertainment - you're a participant rather than an observer. Plus you have to use your brain!
I never played Oregon Trail, but I ended up downloading it after reading the novel. I'm a little afraid to start it because I think it would be a huge distraction! When I downloaded it I found it interesting that the intro said they'd modified the game to be more sensitive toward Native Americans. I think that's pretty cool.
