3) Replace the reading lens (Divineo is a good website)

**Try this, has been working for me for years! - - Place two strips of Scotch (clear) tape each strip an inch long onto the top of the disc.

All three Xenosaga games were good, you can play the third w/o playing the first two, but you'll miss out on some character development and story.

FFX looked great the first time I played it on PS2, I couldn't tell where the in-game movies (cutscenes) ended and the game began.

I didn't much like Kingdom Hearts 2, one was good though. Also, the Shin Megami... games were pretty good.
