The game needs specific graphics for all corporation type structures (specially scientific)
I listened somewhere most of the graphics are still in development, but I'd like to suggest that you make different structures for each corporation type. A steel mill from expansive for example, should be different from a steel mill from scientific. This is specially important for scientific since after you buyout a differnt type of corp and get their structures it's a bit cumbersome to find out if a processing structure is being properly supplied. For the other corporation types this is less important, it's more of an aesthetical improvement than anything else, but it would be great nonetheless.
