I'm not too fond of RTS anymore: it's a genre that's been done to death and usually lacks originality. Usually as Kees says its a case of build up your forces while defending against enemy attacks, then mass-attacking them all at once when you're ready. ;-)
I don't know what Northland will be like, but I'll probably buy it anyway. RTS can be fun at times, even if I prefer real strategy.
