You flail the ball around for so long without hitting anything the machine starts searching for it.
You get saved by the ball save timer more than once on the same ball.
You are trying to make an important shot and after about 25 shots at it and beating the crap out of the same rubber post, your ball finally drains.
A friend of yours holds the grand champion spot on one of your pins for almost a year and you cannot get it back no matter how much you play.
You find yourself cursing and giving obscene gestures to your pins after nearly every game.
Your average playtime on titles that many boast to be 40 minutes or longer are like 2-3 minutes.
You can play the same game 10-12 times in a row and your results do not improve and in fact get worse.
Oh and what I'm describing above is my own experiences, and yes I do suck. Arrrrrggghhh! Why do I love this hobby?
