I had a guy stringing me along on a bonk 3 CD that he said he would sell me for $100. I told him $100 wouldn't be a problem as long as it was in decent condition. Luckily, this was all in person, so I THOUGHT I would get to check it out before purchase. Well, it turned into, "yeah, I haven't found it yet, it's in a box from a recent move". Anyway, 6 trips to the guys store over 8 weeks never materialized anything so I gave up.
Eventually, I got my hands on the super RAREZ third version, for what I though was a decent price. After about 15 minutes, I said to myself, thank god I didn't pay $100 for the CD of this. I was very disappointed in the game.
