idk yet if I want to get this for the xbox one or the 360. I know that there will be more people on the 360 and i know there will probably be less glitches/bugs. But new gen will look so much better. what are you going to do?

Everytime I start my xbox 360, it always has a fuzzy screen display. It's not bad, but you can tell it's a bit fuzzy. And if you look very closely, you can tell the pixels making the fuzzy display is purple. You can't tell it's purple if you're playing regular though, only if you look up very close at the screen. I know it's not my TV, because when I watch TV, I don't get that kind of display.

Also, when I'm playing any of my games, out of nowhere I get a quick purple horizontal line that runs across my screen, but goes away fast. And it happens maybe every 30 minutes or so. What is that?

There is this Gamestop trade-in deal where you trade in 3 games, get an extra $10. I have 6 games to sell, but I don't think you can combine the offer. So my question is this: Can I go to Gamestop, trade in 3 games, get store credit on my card and extra $10, leave, go to another Gamestop, sell the other 3 games, get store credit on my card and another extra $10?
