Earlier quoted context omitted.
There's probably a lot of this going. Comes to mind right now the way the Navy had about two seal teams in the beginning, and then decided to name the next one 'Team 6', to make it look like they had more. I've read about other examples, but can't remember right now.
Not the same thing but similar, a programmer wrote once how he made his software delay the answer to some user action to make it look like the program was hard at work. The process was actually very fast, almost instantaneous, so he added some message like " working - x seconds left ". Maybe it was on HN some years ago...
Just imagine if you were playing chess against an opponent and as soon as you made your carefully planned movement the other player immediately made his move and it was your turn again right away. It feels pretty aggressive, doesn't it?
So I gave players the impression of the computer taking time to think by instituting a random delay (within a given range which I tested until it felt right) before it acted, and I think it felt a lot more natural and less aggressive because of that.
If people are curious about the game, it's easy to find and you can play it online.
