I have to admit, after the initial hype, I've become a little bored of my 360 too.
PGR was a bit of a disappointment in that the online play didn't grab me like it did with PGR2 (where did all the rammers come from??), SP was a lot easier too. (not to mention the freaky x600 res and all the jaggies).
Another title I was looking forward to was Top Spin 2 which turned out to be a big disappointment.
I was blown away by Fight Night 3 at first, very nice looking in places, decent-ish game play at times BUT:
Why no single player ranking sys?
Why do you have to fight on the right even online? (that's when you finally get someone to accept a fight, where the person doesn't quit in the settings menu or during the fight)
Why such a reliance on haymakers?
Why is the SP career boxer unavailable to select online until you retire him?
Why did they introduce those newbie config settings? FN is about fighting with the analog stick, not mashing buttons. At least you should be able to disable particular control config’s online.
It’s as though the games are almost there but they feel very rushed at times. Hopefully something like Test Drive: Unlimited will get me back playing again sometime.
