I think where to get them's been covered above, but omg yes, I love those games so much. :D :D :D

I've mostly been playing them on my Kindle because it's easy to hide under the bed covers while the partner is sleeping and play them without waking him up. (He goes to bed early for work, I don't actually stay up all night playing them in secret. Well. That having been said, I do play them longer than I ought to...)
