Most all MMO's do, there has been a growing trend there, especially.
Almost all new indies do, and their games show immense improvement. A few creative minds sitting behind the Company Desk, inside the Company Cubicle, and under the Company Thumb will never have near the creativity and ideas that the casual gamer sitting at home, not being stressed or pressured can and do. It seems even the Big Guys are recognizing this, and actually do listen to the ideas and suggestions. As has been shown in the past, you lose touch with your base, and you soon lose your company.
But, I agree with the idea that allowing Mods will help, in many ways, when it comes to this. I've seen quite a few games lately that have promoted contests for Modders to create 'expansions' on the game storyline.
And, I can see the point of "companies should never allow [whiners] players alter the course of the game"
This is especially true in ANY game that I've seen/played that had a PVP context.
NOT so true of games such as Fallout.
Besides, the point wasn't to allow players to ALTER the game, but to ADD to the game. And as the Company listens and makes the decisions on how those ideas are incorporated, then you don't get the drastic break from story that you otherwise would.
But at the end of the day, just wondering.... Experience has shown me it can be good, so here's to hoping for the positive.
