Settlers 6

I just downloaded and played the demo. As an old fan of Serf City or Settlers 2, I was expecting a lot from this game. But instead I've got just another boring game. Nothing new, just bigger buildings and better graphics. But where is the creativity?? Where are the guys who invented Serfcity? I want some new ideas from these games, you cannot go just like that to settlers 8,9, 100 by only improving the graphics and adding AOE elements. Have all the ideas in strategy games been used? Are we doomed to play only boring games? Is it worth investing so much work in these new games if they don't stand in time?
