Beat the game several times, but...

I have never finished the credits or got New Game+. Yes, my disc skips intensely on the final credits towards the end and doesn't make it through. I've buffed the disc and everything, doesn't work. Should I really try to get a new disc for New Game+?

[Del Murder]

You should if you want to see all the endings. That is the only different thing a new game+ provides.

New Game+ also lets u breeze by the game since ur already superpowered from beating it. so if u want to go through again and mop the floor with someone that may have given u trouble. go ahead. its a plus
