My only fatigue comes from reading all about the new releases; issues people have; code updates, etc. I'm never going to be a NIB buyer because I prefer buying used. But I keep up with all the threads so I'm generally aware of each game if the times comes to buy. I tend to stay a few years behind each release because I certainly know a game is not finished for years in some instances. For example, I recently bought an HUO Star Trek pro and there's a huge club thread as a resource for any known issues and the code is complete.
I'm fortunate to have a huge back catalog of pins I've never played or hardly played, so I never will need to go NIB for a pinball thrill. Like everyone else, I've noticed the features/toys that have been stripped out compared to earlier pins. I mean, really, most new Stern pins just don't have the cool toys, ball tricks and fun mechs on games like Shadow, Baywatch and Big Hurt in my lineup. You can't play a theme, you play the game.
I am also lucky that I don't get sucked into the hype and frenzy on Pinside surrounding each new release. It's real easy to want to keep up with everyone playing the newest games and want to be involved in the discussion as an owner. It's especially easy having the disposable cash to do so and be one of those guys buying NIB, then trading or selling it a few weeks later, always chasing another pin. But I choose not to, tempting as it may be. Just doesn't make any sense to me.
