Before a 'Future Era' - which I'm indifferent to - I'd like to see the 'Modern Era' explored more deeply. They're doing something in that sense by adding WWI and WWII units, but I'd like see more 'Contemporary' Techs, Units, Buildings and Wonders. Internet is a noteworthy absence, but there are plenty of ideas out there (Telecommunications, Tourism, Airports, Shopping Malls/Supermarkets etc.).
