My wife, back before we were married, was of course interested in my hobby. RPGs aren't at all common here in Korea, and in Japan they're known but it's a really small minority that play them. Most Koreans and Japanese stick to the computer RPGs.
Well, back then, I was still enamored of 3E, but that was just way too much for my wife. Even buying the 3.5 PHB in Japanese (only 3E era book still own) didn't really help. Too much math, too many options, too complicated rules.
A few years later, after I'd rediscovered the joys of Classic D&D, we tried that for a while, and it worked much better. She had an Elf, and some NPC retainers, exploring the Ruins under Zenopus' Tower from the Holmes book. The Elf died (as did lots of the retainers) and was replaced with a Halfling who I think made it to 3rd level. But we played during my wife's pregnancy, and the birth of our son ended that game.
Well, our son's nearly 3 now. And my wife is wondering how to improve her English faster than it has been going. I suggested we restart that D&D campaign, and she agreed. This time, to refresh her with the rules, I think I'll have her read through/play the solo adventure in the Mentzer Basic, then run her through the Ruins of Castle Mistamere, also from the Basic Set (with my new completion of it, available for download over on the right side of the screen).
