I like to either play continents and claim my entire continent as my own and play nice with the other civs, or play pangaea and wipe out my closest 1 or 2 neighbors (declaring all wars before the classical era because that's the way the rules are right now) and then play nice with the rest of the civs.
Take note: as I mentioned in the other thread, I prefer an above average start, not perfect but good enough to kickstart my game, and I used to have to re-roll over and over for days before I found an adequate start on continents or pangaea. Since trying the detailed world mod, I've rolled two maps, one detailed continents and one detailed pangaea, and both had good starts.
