I would group things in this order for myself:
[Like the most]
-playing competitive pinball with groups of four in league or tournaments
-"fixing pinball"
-playing pinball alone
[Like the least]
I'm using this term of fixing pinball very broadly. My preference would be "tweaking to make play perfect". Game "condition" is great of it's there but not all that important. I don't like to "restore" games but I have restored a few. I prefer above average player quality games.
