I feel penalized for wanting to peacefully build a great civilization. As the game stands now, peacefully expanding isn't really an optimal growth strategy. Even if there is good land to move into, doing so too much ultimately slows [if not stops] Social Policy advancements. This seem to be the case even more so on Huge maps. The best option is conquering and puppeting neighbouring cities. MY SUGGESTION: Allow players to build a new city but set it as a Puppet. I believe for [at least] player-built Puppet cities, they should ... ... affect Social Policy cost by 65% of normal. ... incur a -20% growth penalty. ... allow citizen management via the governor (not tile-by-tile). Any thoughts?
