agree! and if you have time yet to read somemore, do not miss out some excellent writeups by Sullla himself here http://www.garath.net/Sullla/MOO/moo.html
As one more note: don't be afraid to do some experimentation to find out which playstyle works best for you. I've found that in Sirian's games he often emphasizes base-building to a much larger extent than I would in similar circumstances. Sometimes this pays off for him, while at other times it's a serious drain on his economy, which might have been better served with another approach. So be flexible and don't get stuck thinking one path to success is always best!
