Games can be assets, but only if/when you sell them. Sort of like your wife's diamond engagement ring. They told you what a great investment it was when you bought it, and maybe it was if you picked the right woman. But WHO is ever going to sell his wife's ring for the cash?? It's lost investment potential simply from a cash perspective.
I think I enjoy the chase more than the actual acquisition (speaking pinballs here!). I enjoy searching for and wheeling and dealing for an elusive game. Once I have it and have shopped it, it usually soon loses a bit of its luster. I may or may not sell it, but most games only get played occasionally once they get shoved into their spot. Some get played more regularly than others because I do, as the bottom line, enjoy pinball. Most times, however, the games provide their greatest enjoyment when the grandkids or other guests come over to play. For them, it's all new and exciting and I get a joy out of watching them play. I have learned in life that possessions rarely provide true lasting satisfaction. There are more important things in life.
