I have a 360 and I've grown to hate it, I really wish I had gotten a PS3 instead. PS3 allows you to play games online for free and one of the things I'm pissed about is that I purchased Resident Evil 5 Gold Edition for 360 which unlike the PS3 version that comes with extra content on disc, this one comes with a code that lets you download the content off Xbox Live for free.
The only problem is I found out by accident once you delete that content from your hard drive you can never get it back, so you basically spend extra money for content that can only be added to one hard drive and once it's gone it's gone forever. I also have a problem with the fact that my 360 came with a wireless controller that constantly needed batteries, and even after buying a wired controller so I wouldn't have to worry about that the controller is messing up on me to the point that I can't play games without the game pausing every few seconds.
I miss the old days when game consoles were simple and did what they were supposed to.
I'm thinking about getting a PS2 and some good classic games that aren't plagued by glitches and bugs. Screw the graphics!
Go to your download history, it should be there so you can download again.
