Since we are looking forward for a Civ6, I hope many fans of the series realize that there are biggish chances for the next civ entry not to include the city states gameplay mechanic. Either eliminate the idea for good or their return in first expansion just like they did with religion or espionaje for bigger sales. Religion and espionage were really important in Civ4 and they left it out in next vanilla, so they could do it again. However I wonder if they could do that and later on bring them back in ,since city-states are pretty important in the overall coding. Also they left out the random events wich were pretty fun. So its not like they improve each game but keeping a lot of content from previous games, they do make some radical changes and some features will be missed. What do you think, are they an absolute must to return? Would it be pretty dull without them? How would you improve their mechanic? IMO they 100% should return with added features.
