I'm with Dagh: grow, grow, grow.
Grab the dyes, grab the insence, concnetrate on the core, scout the continent and readjust as geography makes desirable. I'd love to have a second settler pump up and running soon; let's outbreed the greeks.
I understand what Crakie is saying about not letting MIA get too small, but IF we control the world's only source of dyes, and IF we can grab another resource or two for trade, we may be able to exchange for techs with the other continent and not worry about tech agreements with MIA.
I know that is speculative, so I'm not banking on it.
I can't tell if MIA is overly cautious but genuine, or unreliable and duplicitous. Therefore I assume the latter.
Go along to get along, trust but verify, [insert other folksy wisdom here], and build the Great Grape Fleet for exploration.
