If I only had found it all those years ago... heh.
I think it will work perfect for SC2 too. I'll be surprised if you have to change more than 10 words. Change 50 and you'll have a guide for Age of Mythology. It really is excellent stuff and I'm surprised that the world isn't filled with guides telling you how to do economy and that you are supposed to learn economy first. It brings everything else into place. I actually think that the "next level" is kind of easier. Now that I have my priorities down I should be able to utilize all those strategies I've been reading about all these years.
Though it would be nice to know how to counter a (surprise) BC attack? I got lots of Scouts, despite reading about how lousy they are, and it worked fine. Cosairs are bad against the BC armour. Dragoons won't be able to protect my island expansions. Carriers take very long to build and can be brought down with Yamato if slightly outnumbered. (However: once I got rid of the main BC fleet, I transitioned into Carriers and finished him off)
I tried to shuttle probes, like you say. But managing it at the same time as everything else kind of got the best of me. Getting them out on the island I kind of managed, with some time. Getting them off the island again simply felt like too much work. Though practice makes perfect!
Also: the term "Manyarding". History lesson, please? :)
