I dunno, being in marketing myself, you learn how valuable customer insight truly can be. In short, if you aren't satisfying your customer base's needs, then plain and simple, your product won't sell.
As it translates into KOTOR II: as successful as the first game was, the second release is pivotal. Churn out a game that is too similar to the first, and gamers will become bored. Relase one too different, and again, gamers won't be happy. I am pretty sure we are all crossing our fingers that this release is going to be close enough to KOTOR I that we truly feel it is a continuation of our journey, yet at the same time, feel satisfied that there are the right amount of changes so that we don't feel like we are playing the EXACT same game, only on a different map. If the devs can accomplish both, then they will surely see this franchise flourish for a very long time. (Example: if the initial follow-ups to the first Final Fantasy would have been uber disappointing, we definately would never have seen FF IX, X, X-2, etc.)
Thus, as brilliant as the folks at Obsidian surely are, they would be monsterously idiotic to ignore these boards. I mean, here is a pure, virtually free method to get direct insight into the customers needs and wants (which in the mktg world, is near impossible to find). We are here b/c we want to be here, not because we have been coaxed into some mktg study. These suggestions are coming from the guys who have played KOTOR I extensively, loved it, and are foaming at the mouth already in anticipation of the next installment. Thus, our desires ARE the customer's desires. Believe me, a few copys of this game sent out to those of us who could make this game an even bigger success than the first is immensly less expensive to LucasArts than it would be to have this game flop.... especially when you consider the ammount of money a succesful KOTOR series would generate over the next several years.
Besides.... do you REALLY think they are gonna have a "special thanks" section in the credits that displayed names like "Jedi Killer 9927"???
