You only have so much time to play pinball. Unless you are retired with a ton of time on your hands I recommend you stay clear of anything more then 5-6 games.At my worse I had 12 and games would go weeks with no more then a couple of plays.

Your going to have favorites and you will focus on these and neglect your large collection. More games also will make you dedicate more time to maintenance and repairs. A weight has been lifted downsizing but one issue I found is you get down to the best of what you love about pinball and it's hard to sell them.

I have 5 games and still feel it's too many to play all of them regularly. Best of luck on your collection size choice but I hope someone somewhere reads and decides overdoing it might not be the best idea. More power to the people who have 20 plus games on pinside. I don't understand how you do it but go for it if that makes you happy.
