@Dessire to be fair, in your defence, I love futuristic architecture too. FE/early AF is(/are) my fav. age(s). When talking about vanilla building looks. My 2nd favourites are SA:V colony buildings, with practically all space age colony’s environments, they’re simple amazing. Love all of them for different reasons.
That been said, when it comes down to event buildings I can understand why it’s not feasible for Inno to order their artists to create futuristic skins for buildings. Even if it’s done like Himaji castle. I also can agreed with you for more futuristic architecture in event buildings. The authenticity reasons ship has sailed ages ago (if it was such a big deal, GB’s should’ve been age locked upon introduction of GB’s). A good example is the Arc showing up early in many cities.
Personally I think the real reasons are event themes themselves. Let’s be honest here: st. Patrick’s day (traditional), summer event (pirates), soccer (contemporary Mediterranean vacation), fall (contemporary countryside), fellowship (medieval), Halloween (creepy old ran down stuff), winter event (progressive era), etc. Wild life could incorporate solar punk architecture, like the GB rain forest project did. Without really deviating from the theme. Since it’s mostly nature reserves and preservation themed. Which solar punk does support. Anniversary event is the perfect event for futurism. As it’s celebrating how far the game has come.
To cut it short. Event buildings are tight to a given theme and architecture. Only wild life event could become futuristic. Towards solar punk architectural buildings. Much like the GB rainforest project. Could more events be introduced featuring futurism? Sure, however from the looks of it, the devs clearly have chosen for more variation.
