It is unfortunate, but I have been seeing the attitude expressed on this forum that we should all hope for the quick demise of Civ 5 as this will be the quickest way to get Civ VI into our hands. And, I think that, judging by some of the posts I see here, there are those who not only hope for Civ 5's demise, they encourage it by various means.
If Firaxis is like so many companies though, especially in this economy, one element that is absolutely essential to the ability to financing the development effort of Civ 6, is the success of Civ 5.
I could name a lot of companies, not just gaming companies, others too, that, because of a less than successful product 2 years ago, today are out of business. (Monte Cristo is the first one that comes to mind)
Certainly I do not wish to quiet those who don't like Civ 5 as much as some others, we all have opinions, and CFC is gracious enough to provide us with a forum for their expression. I think most of us would like Civ 5 to be a better game, and we all have our own ideas of how to make it better.
But I will suggest that perhaps some forms of expression, especially those that are likely to discourage people from trying the game, or those that may discourage others from suggesting the game to friends, may be counterproductive in the long run.
Sterling games are produced by strong companies more often that not, and Firaxis needs Civ 5 sales in order to be strong when Civ 6 development time rolls around.
