I noticed that my after researching far enough, that my entertainment building upgrades are actually downgrades when I reach VR centers. I don't understand why the more advanced structure is actually worse? 55% zero G center compared to a 40% morale boost of VR. For that matter VR is even worse than Extreme stadiums two grades earlier at 45%.
So 45% Extreme stadium->55% Zero G center-> 40% VR, that is boggling me. I think I am going to go and trade VR centers to all my opponents to hamper their morale, that's the only good thing I see from getting VR centers.
