Worst port? My friends play FFXIII without any hiccups and It looked fine. If anything Mass Effect 2 made the game seem like a distant memory, I don't care what system it looked better on - it wasn't up to par with ME2's epicness.
Losing crediblity? Because they want money?
Seriously guys, does it hurt so much to see Square-Enix go multiplatform? Is it wrong for other people to get a piece of the pie? I wish people would realize console exclusivity is not the way to go unless someone is lining your pockets. A majority of exclusives are still first/second party - the third party exclusive game on consoles is getting harder and harder to come by unless It's on the PC or Handheld.
It's just that simple.
