...hey wait! Isn't there a Homeworld 2 ship floating around somewhere? And aren't those Viper MKII from Battlestar Galactica? They've only taken one or two things from a different story, why not one from Halo? I'm not asking for a ship (though it would be nice) just one of the guns.
This was touched on by me the other day, the reply was, we are working on murdering the imports with new fresh ships our local designers made. The only reasons the Battlestars and Vipers are around is because the =CR= faction are dug in like WWI trench soldiers.
There are many unique ships on the way I think, the imports are being phased out.
I was going to bring up the MAC gun wouldn't get a good initial reception since it derives from Halo as Gronath said, we want to be unique and fresh without relying on other peoples ideas.
In the end though, we are going to run out of ideas that this game engine can use without crying and making ion storms out of its rectum.
