Maps with multiple continents tend to be a little tougher than Pangeas. Everybody knows about iso and its probably even more difficult cousin, semi-iso. Then there is a situation where you share your continent with 3 rivals, meaning you're on the bigger continent that will likely have the fastest tech pace. Here you can play mostly in a standard fashion. But what about the intermediate situation with 2 rivals? You have neighbors, but you're on the slow continent. You somehow need to get to a good military tech but can't ignore Astro or else you'll fall behind. Attacking too early could be fatal. What would be a typical course of action here?
