As we move towards 8 or 10 billion people on the planet, there's a little less gold per capita. Each one of us will continue to be fighting over an ever smaller percentage of total resources. This is not a happy thought.
I don't really worry about the size of the part much any more. It's nice to have more time to work on the character, and to have big scenes to play. But if there's something playable there, and if it's interesting to do, then that's nice.
