Here is my stance. Repros are definitely a nice alternative to some games. If there had been an option to get a Rayearth repro before I finally found the copy I have, I would have gotten it. I honestly think that most people are against repros cause of the value of some games. If all games were worth nothing, who would really care about repros?
I actually also prefer that they sacrifice sports games to make them too. One less sports game on a shelf = win.
I always assumed that is where the bulk of reused carts came from. You can go to any store that sells games and see dozens of copies of Madden 199* or whatever. I would rather these carts get reused than just tossed out.
