The more I see polls like this, the more I wonder why people bother making them.
Oh, I can tell you why people are doing this.
When the game was released, some people almost immediately identified certain flaws.
The came here and were shouted down. They couldn't be correct with their analyses, and even if so, then this didn't have any meaning since there were hundreds of thousands of happy players outside.
Well, not outside, but at that moment for some strange reason just not playing the game happily, but posting in the forum.
This of course was questioned, and then both sides started polling.
And surprise, surprise, the more polls came up, the longer the game was available, the less the support for the "grandness" of the game seems to have become.
Meanwhile, some people are quite bothered by these polls which always seem to give the same results: significant numbers of players don't like the game.

IMO, interesting polls are things that can be quantified - like how many hours have you played Civ5, or when was the last time you played.
Oh, about these things I can tell you something too.
I started the game at around lunchtime, played some turns, then went to here, read some posts, went back to the game, found a new error (already reported in the bug section) and then again stayed here.
Then I went to the kitchen to cook, had dinner, watched a movie, and now I am here again.
In all these hours the game was running and counts towards my "playtime".

As by now there are 106 hours registered, but I would assume that I've actually spent 20% of these hours *playing*.
This game is just so awfully unbalanced and flawed that I take every chance to do something else, although I am really trying to force myself to explore the mechanics a bit more.
And I wouldn't be too astonished if it were the same case for others, too.
