I should also note that the control tower / hangar complex at the top of the current Barge is an excellent feature, and one that we should move to the new model - the control tower especially.
I really like that model. Makes the barge more detailed. Only thing I don't like is the bio-dome. Its just randomly sticking out of the side and would look nicer if it was on the top or bottom somehow.
The thing about the current in-game barge is that yes, it is poorly made and crude, but it fills the role and looks the part perfectly. Sort of like the old Geb.
I like the biodome, but i do think it should be moved to the top, so it could recive more sunlight no matter which direction the "ship" is facing, and make it have a smaller profile
Replacing fine models with even better models? When the developer prefers to extend already existing ideas in favour of making up new models (modelers block?)
