From my experience, they all run fine on a Windows 7 64-bit system using DOSBox for 1-4 and QuickTime Alternative for part 5.
I'd love to see Quest for Glory released as well.

Love the series on King's Quest. Such nostalgia! Keep it up!

Thanks for the great article, David. I played the King's Quest series as a child, and they were what taught me how to type. (And Space Quest taught me the futility of playing slot machines without a real life save game mechanic..)
The point about the tension in KQ3 is so true. I remember vividly the huge feeling of relief when the wizard finally ate that cat cookie. I'm looking forward to reading more!

Man, these articles are really really really good. I haven't played any King's Quest game (I've played a bit with KQV, but it was a brief experience), but reading this stuff really makes me want to play the whole series. Congratulations, it really is a nice article.
I was waiting for KQ 1, 2 and 3 (and you've made KQ3 seem particularly good), but now I'm so pumped up about playing these games that I'll probably buy 4, 5 and 6 and keep praying for 1, 2 and 3.
