BillChin, if you're reading this thread, I tried your dense-build approach on Regent level, Japan, small random map, sedentary barbs. It's a fun change of pace, so I really appreciate your posting about it. But I'm still not sure whether it suits my play style. It worked fine in the early years, since I was able to out-build my closest rivals, the Chinese. I've squeezed them off most of my continent through a combination of military and cultural victories.
But as a result of my dense build, other civs took much more real estate than I did during the initial expansion phase. They spread three times as far, which counts for a lot more in victory points. What's more, my startup cities are now competing with each other for resource squares. Only one -- my capital -- has made it to pop 12, and I'm about to enter the Industrial Age.
Yes, my other startup cities are packed in close, so there's minimal corruption, but there are also no "go to" cities with massive amounts of production or cash/science output. Even my capital is hemmed in. You say I could 'trim' cities, but I'm loathe to destroy the investments I've put in my mid-sized, close-in cities. Or should I just have not invested in them in the first place? Built no temples, etc?
Now, I may still win: I managed to get the Great Library, and I now enjoy a tech lead & am cranking away with democracy into the Industrial Age. And yes, I've taken over some nice chunks of former Chinese land. But I'm not sure how I'm better off with a smaller civ, with cities packed together, now that the rest of the world is full of civs that expanded traditionally. OTOH, I do have to admit that it's nice to have minimal corruption problems for a change. And yes, it's easy to defend such a compact little empire.
So I have some questions. What type of victory do you seek with this strategy? Do you just go on an endless military campaign to expand your initial small territory? Do you use this strategy on Tiny maps only? I know you're playing on a higher difficulty level than I am, so maybe I'll appreciate it more if I try Emperor or something. Anyway, thanks for posting it; I'll keep plugging away with it. And heck, if I win, a win's a win.
