I'm on about my twentieth actual fort (not counting the tries that failed immediately and hare-brained ideas that were abandoned in minutes) and I find myself increasingly laid back. I've only done about 5 forts in DF2010, so I still haven't mastered the military or hospital and I never use burrows, although I always think I will. I generally go very, very slowly, growing food and mining and making junky trade goods and stockpiling metal, until I hit my pop cap of 100, then I take stock of my population, assign three or four squads, build their gear and start training them. It's not unusual for me to turtle up through a seige or two, watching migrants and caravans get slaughtered, or to have my mayor become a baron before I do anything that I think is noteworthy. My current fort is nine years old, no sieges (just some dark gnomes, very funny) and I still haven't done anything cool. I've mostly had it running in the background while I play Xbox or drink. Now I'm finally starting up my textile industry, so I'll start making custom-dyed uniforms for each of my squads, then I'll train up said squads until they don't suck, then I'll engrave something I guess, until these baby snatchers tell their mates that we're worth invading. I still haven't won a stand-up fight in DF2010, and I'm looking forward to rolling out a few dozen steel-clad drunkards and seeing how they fare.
