I've been complaining about this issue here since 2007 but they still are getting it wrong. I just wish the scaling would be done so that the game speeds have experiences in the same ballpark. 1. Staggered starts go from a ridiculously strong advantage for the player on quick to essentially meaningless on marathon. 2. Gold huts STILL don't scale. 3. Many expeditions don't scale except in the duration of time your explorer has to spend doing them. 80 production reward for 25+ turns of expedition is sort of a joke. I'm also willing to bet the hammer decay issue is the same as it was in Civ IV and Civ V. This doesn't seem like it would be difficult to fix. If balance is the concern, then the scaling doesn't have to be perfectly linear. But the numbers should not remain the same on different game speeds. I know espionage scales (siphon energy seems crazy on marathon to be honest) and I'm not sure about quest rewards. The main point I am trying to make though is that marathon and quick seem like two completely different games, not the same game with different settings. I'm not a fan of that feeling.
