I've just run across Glest and would like to learn how to use it. However, the tutorial is very, very unclear. It tells you what you're expected to do, but there's not even the slightest hint on how to do it. I had to exit and restart it just to get the workers "built" and working, and never did figure out how to "build" a cow, although I finally managed to get a worker to the farm.
I'd like to point out that the purpose of a tutorial is to tell the new user how to do things; if you have to keep going back to the start over and over to work out how to get the tasks done, there's no real point in using the tutorial.
