I just got here! Was it decided the battle system would always have you have a hand in it, or that it would always auto-resolve (like in GCII)?
They haven't said exactly what it is. They have said that it's not MOO2 style "control individual ships" combat.
This is what has been said is in:
"Tridus: Given all the threads on it and the endless speculation... is there going to be any player control/influence of ship combat at all? If so, what form will that take? (aka: Tactical combat?)
Paul Boyer, lead designer: At first glance space combat in GC3 will appear similar to that in GC2; ships will fly around in fleets, when ships from separate powers meet in a single tile they fight it out. Two fleets enter, one fleet leaves. Where GC3 will be different is how the battles are fought. If battles are auto-resolved, not much will appear different, but once fleets meet in the battle screen everything changes.
In GC3 we will introduce the ability to assign roles to ships, giving them unique behaviors in fleet battles. These different behaviors will be used to specialize ships and create checks and balances, making the composition of your fleet almost as important as what weapons or defenses it has."
