I am just now getting ready to start the Modern age. 1.1.0 came out but I am going to avoid Great Britain, and the new Cultural Victory since it changed so significantly (I'll pick some up, but not focus on it). I’ve played France (Cultural victory) and America (Economic) in my previous games, and I want to try something new. I have been mostly peaceful except for an early war against Friedrich's Egypt, so I am going to try for a Science victory, but be prepared to shift to Military if the AI get in the way (I don't think that's likely, I have a major advantage in settlements from the last age). Both will require good production, so Prussia sounds interesting, I like the idea of the Staatseisenbahn for production, and Stukas if I need to go to war, air units are a lot of fun in modern warfare.
I have 3 legacy points for each area, I upgraded several towns to cities at the end of the last era so I can use the Treasure Fleet GA and keep 6 cities. I'll go through the rest of my legacies once I start the Modern age and look at the map.
