Why should I use outposts instead of just placing a new city on the same spot?
Magog, in your next game give this a try.
1. Find a good city starting spot, look for a 5/3 or better, preferably by a river (so you can build a Dock and maybe Water Wheel).
2. Invest in major city-building research, try to get stuff to make yourself grow faster.
3. Spread some outposts around to control resources and link to your major city. More grain is especially good.
4. Try to find or make an Administrator III hero and then park him in town. If there is nobody handy then just pick some schlub and level them up for the purpose.
5. Let your city grow to stage four before founding a new city. If you are used to having a lot of cities this will seem to happen extremely fast. What usually happens to me is I never found another city, instead I go to war with a neighbor and take theirs as my 2nd + cities. if you do this don't be afraid to raze the crappy ones.
This style of building a Metropolis will develop a true monster of a main city for you. Incredible research (comes from population, and yours is huge), cheap maintenance (one workshop etc, not six in six different cities), access to the very high end city bonuses (save your game before hitting L5 so you can view the options you might have never seen before) and a single point of failure that you need to defend.
If you haven't tried it yet, a summoner hero can be especially nice with this combo since they don't need early army units to be effective. Summoner + Earth / Fire and another flavor of your choice is pretty strong. You'll need to make a custom hero to get the Summoner option as none of the base ones start with that. One game I had a summoner walking around with a L13+ Earth Elemental, that thing had something like 300 HP and made an incredible tank for me while my summoner nuked the enemy from safety.
