There was a game that I closely followed the development for that was in the end, basically a victim of design-by-committee. The game was Tribes Vengeance. Basically the developers, Irrational Games, was in close contact with the TribalWar and other forums to help them design it more in the vein of the original series of games by Dynamix.
At great length, members of the forum picked apart various mechanics they disliked and Irrational adapted...quite a bit. Specifically concerning weapon feel, movement feel, and certain mechanics.
In the end, Irrational ended up with a game that tried to be everything to everyone, and while it was a thoroughly decent experience, it was, well, decent.
Nobody plays Tribes Vengeance anymore.
But plenty of people play the two original Tribes games, even today. I think what my point is, is while community input and suggestions are excellent, and indeed important things, a game will never turn out well unless a developer has the backbone to, despite all the naysayers, see their own collective vision to fruition. Trying to adapt every good suggestion that comes along into your game will result in something that's unfocused and, at best, decent; at worst, all over the place.
We don't need a poll. Let Stardock do their jobs. And if you aren't satisfied with their design vision or the job they do, there are plenty of other developers willing and happy to sell games to you in the future.
