Facilities Restrictions

[Makinus]

I am thinking in a way to restrict certain facilities to certain planet sizes/types, but i'm having problems to make them work.

My ide is the folowing: limit some facilities, like shipyards, to certain planet sizes (Large and Above)....

Maybe if we make a very "weak" shipyard facility that needs additional "modules" that will boost it's production, making them useless to build in planets that don't support enough facilities....

My major problem is with the AI, how we can change it to work efficiently with these modifications?

If you have any ideas, please share with me, i'm new in modding and don't know a lot about the AI files.....

Thanks
