Excellent tutorial. Nothing else new to report though. Andrew and Leo seemed to have covered it all. I also agree with splitting them up into campaigns (or if possible, a selection of tutorials when you click the tutorial button). Sections can be very usfull cause too much info at once is tricky to remember. So different tutorials on groups, for eg: swarm/workers/explorers, and warriors/barrack, racetrack/swimming pool, inns/resources(wheat/fruit), defence/attack and other things (not in that order) would be very good.
