There is no way you can accurately gauge the responsiveness and feedback of a game by merely watching someone else play it. It's like watching someone else test drive a car and telling the salesman "Yeah I'm really sold on how that one feels. Let's start the paperwork!"
Terrible analogy. Playing a game has nearly no similarities to driving a car.
excluding motion control games out of the equation. I'd bet any amount of money on the assumption that you've never watched an LP before buying a game, and found the game to be completely different when playing.
Of course, you'll most likely it.
You can get an extremely good judgement, and make an extremely safe purchase by watching an LP.
