I'm with Kush on the scaling as well because this is Freespace so too bad, gigantic strike craft would look retarded and you know it. Not to mention, are you telling me the people are like 6 meters tall lol? Don't be rediculous, and talk about being easy to hit targets as well.
Frigates and capital ships can stay at the same scale but strike craft are going to be scaled appropriately for Freespace gameplay. I personally think having bigger frigates and capital ships makes it better. In a 20m fighter you can fly close to them and through gaps, hangar bays, and stuff like that in a 60m fighter you would just crash into the sides.
