Yep, I've found that at maso on smaller maps the Drengin strategy of extortion works really well. Because I can't get as many good trades with the minor AND major civs, the Drengin can surge ahead as they rake in the credits. One strategy I am trying is becoming Pure Evil and then setting up my trade routes only with them. They seem to then reciprocate and before you know it there is a love in. Much earlier now, I am conquering the minor civs because they are just a cash cow for the Drengins. In fact, it pays to attack the weak civs ASAP so that the Drengin's strategy of extortion loses its value quickly.
To get a military lead (or at least close to the Drengins) early in the game, I am throwing all my credits into tech, and trading with every civ for freighters and military vessels.
Oh, and your poetry is really beautiful.
