If you're setting a game during the Cuban Missile Crisis, look through a library. find out what people were wearing, what other issues were in the news, how houses were furnished, what cars were being driven. Especially include things which now seem foreign.

I like to employ a form of repetition, in which the same elements recur but in different and unexpected ways. rather than being discarded as soon as they are understood or passed over.

This means keeping many trails open at once, inevitably requiring a fairly 'parallel' plot. This plot should be discovered rather than announced, so show, don't tell.

I'm rather pleased with the new manuals. I see Inform now as a gauche young adult, having got past the stage of growing out of his shoes every few months.

For a fortnight nobody at all emailed me, or posted a follow-up. Doesn't anyone care, I thought? It turned out my newsreader was broken, and hadn't posted at all.

I try to make puzzles range all the way from easy to hard, and to leave many open at once.

At the end of April I archived 'Curses' and Inform, and announced them on the newsgroups.
