A nice game on Theta . It seems to demonstrate the biggest cause of wins/losses in 1v1 ranked for FA players: overextending the ACU without support. Also interesting to see that more factories doesn't always equal more production, if you don't have the resources (although I will admit to getting a little tunnel-visioned and being slow to build the last few landfacts). I actually had about the same number of units as he did throughout.
Near the end, he was doing better in terms of eco and production, probably because of your losing your grip on the southern mexes. Anyways, you're right about the outcome. Had he supported his comm more, he would have had a much better chance.
