Me and my cousin have the oppersite, and yet still admire the games we can't get on our consoles.
He loves left4dead on my xbox. I love heavyrain and also dynasty warriors (7 empires) which i cant get on xbox
Just sucks that there are so many great things that are restricted to each.
We found a lot of download content is always out on xbox first, like the crap load of content that skyrim got before ps3. But he hates paying monthly for it so he sticks to ps3.
Then you got the people who war against each other because they hate the other console lol. Ps3 for when it got hacked and xbox because they used to get red rings of death.
If you like zombies then go with xbox.
Best graphics personally goes to ps3.
Plus if you got a psp, then ps3 is a good thing to go with.
To this day, I still stick by my xbox. Despite getting my ps3 for free soon xD
