I had a copy of 3D Construction Kit way back when. I had planned to make a game using it – my first non-text adventure, in fact. It took 15 minutes to load from tape and the tape wasn’t great quality, so often you would set it away, go off to do something else while it loaded and then come back to find “Read Error B” on the screen. It was then either reset the machine and try loading it again, or give up.

Usually, I gave up. Hence The Life of Nob T. Mouse became a text adventure written in Graphic Adventure Creator rather than the cool 3D adventure I had planned. Oh well. That’s how these things go.
