Alright, so a few of you knew I was doing this (and I expect a few more guessed it, after an earlier forum discussion).
I wrote a very long, in-depth history of sim games for Ars Technica. Part one has just been published. Check it out:

(Yes, I'm aware that the screenshot of SimAnt is captioned incorrectly. There are 73 screenshots across the two parts, so there was bound to be an error somewhere. And I don't have the privileges to fix it.)
