Genres which used to be exciting and novel are now overwrought and unoriginal. Gamers who used to be excited are now jaded. A little of column A, and a little of column B. Depends on the criteria used. (Hint: Requiring shinier graphics every year to get the same enjoyment resembles another hobby).
Also, Sturgeon's Law did not cease being in effect.
Personally, I find certain games breed less enticing communities, and feel that similar games would benefit by attempting to weed out, through game functionality, those types of antagonizing players. If they can deal with the changes (and perhaps develop themselves appropriately), then the measures would not be a strict bar of their participation, only a discouragement. (Example: Skill-point-based rpgs without respecs {the light/dark system of TOR comes to mind for another})
I cannot say at this time that Civilization is one of those games (although I should probably play more ciV just to be sure).
