This is really ridiculous. I just started with Trajan, had two cities up, two luxury resources and was down amenities less than 50 turns into the game. Couldn't even trade because no other leaders had ANY luxury resources yet. Hit with a surprise war and now housing too low. I'm playing on the easiest level, and I can't even advance without cities on the verge of rioting. I need to progress towards an entertainment district yet have to pump out troops for defense whilst the cities are complaining of a lack of amenities I can't acquire. I shudder to think what the more difficult levels are like. I'm on the verge of just giving this game up.
