If I find a franchise that I dislike from a certain publisher/developer I, like most sane people, would probably just avoid it all together. Buying used is a personal choice and as many above have stated doesn't affect much at all. For me I buy new games mostly, unless I am unable to. For example, a while back I got the xenosaga trilogy used for $35 on ps2, the reason for this was buying it new would have costed me a flipping chunk of my wallet and though I really enjoyed the franchise, buying a trilogy roughly worth $200 isn't something I can justify purchasing new (Though if they put out an HD collection of the trilogy in this current gen, or would it past gen at this point? I would purchase that collection brand new on the spot.) so it all depends on the circumstances.
