A copy with ripped manual is a good deal at $30? I have a spare copy in better condition I'll sell for the same price (plus shipping).
I know how it is with the collecting impulse. When I bought a PS2 and decided to start playing through PS1 games I missed, within a couple months I reached 30 games. It was embarrassing, considering that I didn't play any of them except Tekken and Raiden Project for over a year! I was in such a hurry to buy them all, then I didn't play them. I have rectified that, as I have currently completed 13 of my 44 games, and am working through at least one on any given day.
I currently playing Tomb Raider. I just finished "Saint Francis Folly" and, damn, did that level annoy me. It was mostly my own fault, as almost all my deaths were due to pressing the wrong button. The level has plenty of long drops that kill you if you press the wrong button. On each level, I think I am clever and have found all the secrets, then the summary screen always informs me that I found maybe half of them. Fortunately, the game doesn't actually track total percent "complete", or I'd be driving myself mad trying to find everything.
