I don't think it would hurt, I wouldn't want to see Fable style where it changes the way the game looks and feels but somewhere in the character info I wouldn't mind seeing it e.g.
"Ow look, my Karma says I'm a ruthless killer. Would you look at that"
or
"I knew I was whiter than white, I'm so good the sun shines out of my REAR END" (nice boys don't swear)
Lol yeah, i kind of agree with you, I don't want it to be so it changes the way the game feels but only like, that you get different reactions from people depending on your karma and fame
Although I wouldn't want it to be evil or good in that way so if you are good you never swear, never fight, are nice to enemies... and if you are evil I wouldn't want it to be like I am a mindless murderer but more like sinister "smart" evil
And good would be that you are more noble and have honor e.c.t
I think you understand what I mean
