No, I don't know the games: that's the problem. And I remember my Amazon account being charged, but I don't remember which games I supported.
I know Tex Murphy is one of them I did support. There also was Broken Sword and ...??? All came about the same time frame.
I'm just surprised that if I paid through Amazon, I can't find any record of that on their site, or I'm missing it.
I found it by checking my old emails: there was a confirmation from Amazon confirming my donations!
The answer is....chocolate! Who cares what the question is.....
