To start off I have been a PlayStation player my whole life. I bought the Xbox 360 mainly for the Kinect so my daughter (and her parents) could enjoy it. I played the second game of this series briefly and liked it so was excited to try this one (and maybe keep it for like $13).
I made it 20 minutes into the story before sending it back. I understand people have highly rated this game due to multi-player, but I have NEVER been interested to play with other "nerds" around the world and there is NO WAY with gameplay this bad, multi-player could save it.
I've always understood the controller scheme was different between Xbox and PS3 and I can learn any scheme in a short amount of time. The main problem was the graphics. No kidding PS2 quality may be better than the Xbox (with the same TV and cabling as the PS3) and just poor dialog and characters. I want to care about who I am playing as and these characters (even after 3 titles) are just somehow cheesy and annoying and (excuse the expression if you are one) meat heads.
Take a minute to play The Last of Us, Borderlands 1 or 2, Modern Warfare 2 or 3, Far Cry 3, or Fallout 3 (just to name a few) and you will be a PS3 person for life.
I recently experienced this same sensation when buying an iPad for the first time late last year and having an iPhone as my work phone.
If this truly is a staple of the Xbox, please Please PLEASE just sell your Xbox (360 or One) and get a PS3 (or better yet 4). You will be SOOOO glad you did.
