Quoted from SMI3:What Pinball do you Think will be my biggest earner, I am located in a amusement park. 2.800.000 guests in the park early.
Just for info WWE LE was my top dog the year it came out.
There seems to be a bit of confusion in your question. Some people are answering it as if you own all these on route already and you are having us guess which will earn the most (Star Wars). Others are answering like you are asking which of these you should put on a new route (Iron Man). So can you clear up which question you are asking?
