Talking bout Armada 2526... and anyone who is currently playing it.
OK. Custom game setup in Armada has these choices:
Number of players: Choose up to 12. Each race has different traits, perks, and flaws that are listed.
Number of turns: You can turn this up to 1,000,000! One million that is.
Level: Easy, normal, hard, expert.
Map: Random, tutorial, 12 tribes scenario.
Star density: Very sparse, sparse, normal, dense, very dense.
Size: 8 choices that range from 40x40 to 500x500.
Map type: Uniform, dense center, very dense center.
Those are all of the choices for a custom game.
In a custom("sandbox") the number of AI players is limited by your computer system. You can have 2 or 10 or 20 or 50 or 100 or 500 or more maybe. 12 is not the limit. 12 is the number of races available. More than 12 AI players uses the 12 race names with a Roman numeral after the name.
