I love the Implosion map (65 stars) because of the way you can block off the front of your "area" and make massive fortifications for the computer to smash against. Does anyone know of a larger map with a similar style of play? I'd love to do something with a huge system (100+ stars) and only 1 or 2 entrance paths to each empire's homeworld. I don't like multi star maps, and the "Random Vast" map is just too capricious.
