My two cents worth, I started collecting pins in the early ninetys. I had 13 at one time, I had swapped games, sold games, and a divorce caused me to sell all my games. I am now rebuilding my collection up to seven now.
But one thing I have learned, its your call, play a bunch find what you like and buy what you like, there is always someone going to say, what did you buy that for?? That is the beauty of pinball every game appeals to someone.
Love the game, Love the choice you have, love the challenge to own your dream!
