I think the District system has opened Civ up to incredible possibilities. The thing I have to keep reminding myself is this the Civ 6 base game. I can't even imagine what this game will be like when fully fleshed out it with its likely 2 expansion packs (fingers crossed). I am picturing, for example, how in expansion packs we might see Corporations make their return in the form of Districts, or what the U.N. will look like if they give that an entire expansion pack. Plus the original ideas I'm sure they have about things we haven't thought of. Will we get a Civ 6 Venice? Time will tell.
