Yep, I started out with the intention of just getting one...BSD...that plan failed miserably as I left the show I got it at with 2 machines :p...then I said 6 was the absolute capacity I could fit in this house...that became 8 (the two with easily removable heads went to a back room), and I have a 9th on the way whenever my ACNC is ready.
But pinball has been a gift that keeps on giving...
At 8 machines and spending many sleepless nights working on mods, my bitchy ex GF said, "You don't need EIGHT F$%*ING PINBALL MACHINES!!!" (she thought we needed a 5th couch) and left me the morning after one of my up all nighters to get a mod run out on time (knew her 11 years).
Current GF (since June) supports my pinball addiction, and as we talk about her moving in with me, I want to give her lots of her own space in the house, and I tell her I know I don't have room for more pinball machines. I tell her, you can have these rooms, this space, etc., and she says, "I don't need all that space...what are you going to put *there*?" I say I have nothing to put *there*. She says, "Well then you have room for more pinball machines!"
She's also gorgeous (IMO), incredibly giving, makes me laugh like nobody has been able to before, yadda yadda... -- In other words--pinball helped me dodge a bullet
