Bought Mass Effect 3 used for the 360 and it comes with 2 DVDs.
The first DVD was perfect. Everything went smooth, no problem whatsoever. When I get to the point that the second DVD is needed, thing crashes. Console can't read the disc.
And it was too late to ask for a refund at that point.
Had to purchase a second ME3 copy and, while this time it worked, the second DVD was all kind of craziness. Bugs, glitches, heavy stuttering, and an insane amount of problems. First DVD, however, had none of the above. I beat the game, eventually. But while I didn't find the second copy that bad (as the craziness, at times, was too funny), the first one burned me bad. It was a major turn off, really.
Another experience was with Dead or Alive Xtreme 2. Not very interesting, but first disc didn't work. Bought a second copy. Second copy freeze every single time the game boots for the first time. Bought a third copy. Console refuses to read disc. Fourth copy? This one finally works. Some weird shit here.
