I think the word you're looking for is "narrow-minded", if you wanna insult me do it right. We're all single minded unless you have evolved to a greater being and have two consciences.
And what else am I suppose to base my opinion from? Playing the game? The game isn't released. If it was, then I'd try a demo. Since it's not, I'll just watch videos that I see linked. I'm not really interested in the game to look it up, but if someone links a video and expects me to love the game from the video, then that is pretty -narrow-minded-. I didn't go into the TSW thread and bash it, because I don't care about the game, neither negatively or positively. But if you link a video of the game, then I will base my opinion on what I see, and you can't expect me to love the game, especially when the video makes the game look like it's aimed at horny teenagers.
And also, it's not like that video is any old random fan made video. It's a video the devs chose to represent their game at a convention/public event... you'd think they'd choose something more interesting.
