So far my R3 games also no problem even though i've been buying R3 games since 07 when I found out they were cheaper than R1.

Normally I press the center thing in before putting the disc so the center of the disc doesn't take any stress. Has worked so far and am just hoping it doesn't happen to me.

Won't the seller rugi alot that way?

I'm not sure if I am right, but someone once told me that the disc is okay, but the center of the box is very rigid.

Is this true? Personally, I think so since most of my games which I handle really carefully never crack.

Yup, most people are willing to put their games in plastic sleeves as they are easy to find, but don't want their games to look like Jack Sparrow one

Lens failure is RM300 because that is how much the lens costs. IINM, the warranty only gives you free labor charges and free replacement (if MB problem) but you have to pay for things like new lens.
