Regarding Czechoslovakia, I would recommend a modern building... maybe an Airport that doesn't give a health reduction, or an improved Recycling Center. Something that hasn't been done yet.
Hmmm...I like the idea of using a building that hasn't been done (or at least, done rarely).
Let me look into it.
For the buildings we do have, do you have bonuses for them all? If so, email me what you have and I'll start building the XML.
