Why not increase the mercenary's stocks of food? That'll balance out the running-out-of-food dilemma at least. And I beg to differ on your NW ranges; $400m is none too difficult so long as you time your runs well. That's somewhat a point of skill, however. But realize this; on 100,000 land, a leader will take longer to reach the same networth as an indier. Multiple times as many turns. Just as resources are typically consumed slower than they're produced (useful for net gain), it'll still take a good bit longer to either Goldmine or Feast your way to the same $400m or so NW achievable on that much land.
