Modern Art as a tech covers the various art movements that sprung up after Realism; techs need to have content in order to make them worth researching, and individual techs for art movements just don't cut it in my opinion. An umbrella tech can gather enough stuff to be worth researching in its own right, and not just because it's a prerequisite to another tech. One of the reasons I created Modern Art was to hook Realism into the tech tree by eventually leading to Mass Media. This is how I plan to set it up: Era: Industrial Requirements: Industrialism + Psychology + Realism Leads to: Mass Media Allows: Bauhaus School (wonder), Cristo Redentor (wonder) Bonuses: +2 from all Art Gallery, Artists' Guild, Theatre Cristo Redentor moves here from Radio. It fits the technology and it fits the timing better (dedicated 1931, with the Modern Art technology coming along around 1919). Bauhaus School is a new Wonder. It combines form and function, giving you +2 from all Artist specialists and +2 from all Engineer specialists. I'd like it to give + to Engineers, but the XML doesn't exist for that right now. I may put a free Great Artist here as well, but that will come later as part of a proposal to rebalance all of the free Great People on the tech tree. It's very unbalanced right now, with 5 Great Scientists and only 1 Great Artist.
