Well I have to go against the flow on this one. Yes I love real pinball better, but I am never going to be able to afford or have the room for 200+ machines. So here is my reasons for:
1: My home built Virtual-pin allows me to play all of the most popular machines anytime I want.
2: It helps me decide which real pins are really fun and worth actually buying.
3. Takes up a lot less space
4. It's a huge hit when I have party's
I don't think VP's physics will ever match a real pinball, but they are pretty close.
