The moment I stopped retro game collecting is the moment I took a game to the counter and the guy pulled up ebay on his phone to check the current prices. My guy I could have just bought it on ebay if that was my goal.
That really ruins the fun of hunting down a good deal. I sure miss the days when someone at a flea market had a box of NES games for $3 each, and you could sift through and find stuff you don’t have yet. Those days are long, long gone.
