An evolving building that just has culture/pop/coins doesn't sound very inventive. I know a lot of old-school grand prizes were just culture/pop, but it escapes me why everything has to be an evolving building now. I'm not against the idea of an evolving building, but I'm not sure why when they have an idea Inno uses it constantly. It would be so much more interesting if one event was an evolving building, the next was a set, the next was something else. Then they could come back to the same ideas for a long time without them losing novelty.
I don't mind the building, but let's face it... it's a tree. It should be a regular 3x3 culture/pop hybrid at the end of a 10 day mini event.
And as for the shuffle board... Sometimes I think they're gathered round in the design phase and someone goes "Hey, you know what would annoy absolutely everyone, so it'll be funny..."
Positives: Work in progress. I'll come back to you.
