Not counting my first, I’ve been down to one set-up game a handful of times (TSPP, AMH). There are definitely positives, like getting to know a game really well, which can be a blessing for deep games. I also think I play pinball more with fewer games, which sounds odd. Time is a challenge, so perhaps just quicker and easier with fewer. I’ve had just one for over a year by choice, but ready to get the next game, so it didn’t last!
