Why Da Capo? I looked through my wishlist first to see if there are any games from 1979 on them. There weren't, although I am after a number of games from the Seventies. So I entered the number into the search function, and it took me a while to understand why this popped up: It's game number 1979 in the database.
In 1979, I went to Poland for the first time. I was nine years old. We took a ship from Germany (Kiel, maybe?) to Danzig, so we could avoid the East German border annoyances. I remember that on one leg of the trip, the wind was so strong that pretty much everyone except my sister, another child and me stayed inside the cabin. The three of us chatted and played among stacks of seasickness bags (which I later started a sizable collection of). Another memory from the trip is playing with some Polish kids in a village. There were many frogs around there, so we caught some and put them into a kind of mud castle we had built. It was easy for them to jump over the walls, but some decided to stay for a while. We also visited the house my mother had lived in until the age of seven.
Another important event in 1979 was the first Spiel des Jahres, Hase und Igel (which had been published several years earlier in Britain, though, so there is a hole in my collection for that year). That award shaped the gaming world quite a bit, as most of us know.
