A few games comes to mind for me. One was the good ol Iron Man Classic. I got a ton of shit for that game and everyone thought it was a complete dog without the magnets,etc. I think I paid $2600 for it and people instantly said it was only worth $1700 and I over payed & got screwed. It was really difficult(near impossible) to get rid of. I ended up using it as trade bait for a concrete job and received $3500 trade for it. Would I buy another Iron Man Classic-No Did I enjoy it while I had it-Yes
Another one was Skateball. I had my wife play O-dins CQ Skateball in Cali and she fell in love with it and said she wanted to get one. So I started the hunt for a Skateball. I ended up finding a real nice one and brought it home. Weeks turned into months and guess what? The wife did not play Skateball like she said she would and it started to collect dust. I ended up losing $400 on that one and the worst part was I was offered a Nine Ball for it in trade and I declined(talk about regrets).
My other regret was a re-imported Johnny Mnemonic. I got a good deal on it but I probably should have opened up the hood and had a better look. I think every socket had corrosion and rust from container storage, the cabinet was faded bad and it was a shitty playing game with the slow glove. It did help me realize you pay for what you get and sometimes a bargain turns into a jalopy. Live and learn
