I'm going to describe this in traditional bug-reporting fasion.  You guys see if you can replicate it.

Started a new game (single player) using the Huge Random Map.  I locked out all the computers exept for the last one.  This one I set to a random race, easy fortifier, different team than me and teams unlocked.  Resources were set to high, research set to fast, speed normal.

I started the game, a sound effect played in the middle of the load screen, and boom, I had won the game without even seeing the map!

I'm assuming it has something to do with the fact that I set myself up with an incredibly easy opponent on an incredibly huge map.  I did this as sort of a proof of concept kind of thing (I have a way of breaking software just for fun).

Also, all the achievements that involved winning the game without building any of something (strike craft, capital ships, yadda yadda) were all completed, as well as Ensign (beat the game TEC).

I am willing to file this under the "strange but not a debilitating flaw" category, but I thought I would let the devs know, just in case they were interested.
