Homeworld is a great 3D RTS game you should try it out if you get the chance wedge. Some of the mods for it are so cool.
Scheherazade, I have been in the process of adjusting game stats for a while now. Arrow needs to go. Has four weapons opposed to the Darkets two. Arrow clobbers Darket always. Got tired of it. Gets worse when you have large groups of both. So my mod idea will have Ferret vs. Krant instead for better play balance. No longer using exact per cic stats for the ships weapons anymore. Makes the fighters seem too powerful. Bombers are the powerful units with the torp or dumbfire missile.
I figure the Bloodfang and Excalibur class will have the firepower of bombers with the flight and movement of a fighter.
Check out the shiplist at my mod forums. I have lots of units in the mod. Working on texturing now a massive project.
