Blu ray does not make a game better. In actuallity, it makes for much longer loading times. Take a look at Devil May Cry 4. The PS3 version makes you install most of the game on to the hard drive before you play. Now this wouldn't be so bad, if it didn't take 20-25 minutes for it to install. 90% of the games released on Blu Ray would still fit on a 360 DVD.
Yes, that is right, if you want to play DMC4 on the PS3, you have to wait for a fucking half hour. On the 360, you can start playing as soon as you insert the disc.
The 360 has better games, a better controller, and a much better online service. There are optional add ons for the 360, but NONE of them are required for you to play a game.
