Castle Wolfenstein was released on the Apple II way back in 1981, but I didn’t get a chance to play it until it was ported to the Commodore 64. My friend picked up a copy and would not shut up about it. Watching him play was slightly painful because of the load times and collision issues, but I admired his patience in ignoring those issues and seeing the potential in the game.
When I finally got to play it, I was horrible at it, but I saw the potential and when Wolfenstein 3-D was released it was largely the positive association I had with the original that made me pick it up.
Here is one of the famous launch year computer ads that appeared in Computer Gaming World. Everything about how they describe this game appeals to me still.
