Xbox 360 not returned to me

Sorry but no one here can help.You will need to keep phoning support as they are the only ones who can deal with this.

It depends. A lot of people play both. When they buy a new console, they keep their old system so they can enjoy the exclusives and features of both (or all three). And then some sell there old system because they feel like "moving on" or like they are "replacing"
their older system with something new and fun. I used to own a PS3, later switched to a 360... and was in your exact shoes.

I sold my PS3. But for good reasons. To be honest, most people who play enough video games should keep both systems to get the most out of the video game experience. But at the time, the only good games out for the PS3 were Metal Gear Solid 4 and Uncharted
1... and I played and beat those already. At the time, the 360's exclusives were matched. At the time, 9/10 of my library were 3rd party games anyway, and I loved earning achievements for those games for a change.--I even repurchased a few I previously owned
for my PS3 on my new 360. Most of all though, I needed money. I ended up selling my PS3 and my games for $350.

Nobody has to choose, but to fully enjoy and take advantage of just one system and focus one's time and money on it like I have with my 360, I couldn't possibly see anyone doing the same with two systems. For me, I decided to choose so I could focus all my
time and energy on one. and I got to know my 360 better than most who decided to keep both. and I haven't regretted doing so. But I've been out of the PS3 community for a while now. Nothing wrong with buying a used Slim PS3 for a smooth $175 and renting the
exclusives I missed. That's all I'm interested in concerning the PS3 now. The way I see it, I saved a lot of money and made the most out of my gaming. But this route isn't for everyone...

I would keep both. Why deprive yourself of one consoles games if you can enjoy the best of both. The good thing about PS3 is at least once you purchase the console it really doesn't cost much except for the electric bill and games. So it is not like that
console would cost you money if you didn't turn it on for a few weeks.

Also, I am just speculating here but if you are needing some quick cash, my advice is to never sell something you are questionable about letting go in desperation, you will only regret it once that money is gone.

Of course this is just my opinion, and you can do what you want. Again, I'd keep both unless you know for sure one console will not offer you any entertainment.

I own both and despite I use my 360 a little more then my PS3 I still enjoying owning both and using both

If you have a PS3 there is no point getting a 360 unless you like Gears and Halo that much, unless you have friends with a 360 you plan to play with.
