People keep telling me that I should regret selling LOTR and Funhouse, but I think that's only because my machines are in really nice shape. I don't miss either one. Smacking my balls in Rudy's face was getting old, and LOTR caused me to burn a Christmas roast because the freaking game took 45 minutes to complete...and that was with the outlanes wide open. (And if I heard "The path! Of the dead!" one more time, I think I was going to stick forks in my eyeballs.) I do think somebody needs to mod that floppy tower in the back right corner with a dildo, because that would be REALLY funny whenever you get the ball in there. A free beer to anybody who does it and sends me a video.
It is tougher to sell machines that you spent four months of your life lovingly restoring, but it gets easier every time you do it. So, in short: Nope. No regrets here.
