Dead Rising
Unfortunately this is the best condition Dead Rising steelbook I could find. Every time I have seem them while out shopping they have been in dreadful condition. I will let some pictures do the talking:

If you are a picky collector I would not recommend this steelbook. I would consider it "okay" condition by my standards, definitely not a display piece. No dents that I can see however.
Crackdown 2
I would say very good condition. No dents. There are barely any scratches I can see although some of the art work has chipped off in the top left corner but it is nothing major. That is the only damage I can see.

This is the largest scratch I found find which you cannot see head on, only at a certain angle:

I'm being as honest as I can as I don't want to sell anything under false circumstances.
