Hi,
Just jumped over here from the 'minefield' thread. That discussion made me think that it'd be nice to have a few more defensive structures. I did a quick search and didn't find anyone mention this, but how about having some buildable missle battery platforms that launch missles. They would be similar to the gauss cannon platforms, only the missles would obviously be slower but pack more of a punch, and would be guided. If you want to get really interesting, you could allow research for different kind of missle types, which could be chosen as individual batteries on the platforms, much the same way we pick between fighters and bombers in a hangar base. For example, you could choose between cruise missles(heavy punch, slow moving, anti-cruiser/capitol ship missles: 1 shot kills a frigate, 4 to kill a cruiser, 8 to kill a capitol ship or something like that), radiation missles (large area of effect but less damage) or homing missles (fast and agile anti-fighter missles). Larger missles like the radiation and cruise missle could be targetted by Flak frigates and fighters. I think this would play well with the theme of Sins which is strategic fleet composition.
Thoughts, comments?
