So the technology in game still says it unlocks tourism, but I have not noticed any change when I research it (other than building the Port of Call).  In previous iterations, the tech would actually generate tourism at each planet.  Now it seems that they don't unless you  build a tourism specific building (Port of Call/Paxton's Emporium etc).

Am I missing something here?  Doesn't Paxton's still generate tourism if you build it prior to researching the tourism tech? 

If you were build a custom race with bonuses to tourism, would that change how it operates at all?

Thanks in advance!
