Quoted from trk12fire:
So people are just getting Deadpool machines in and playing them. I have pinball machines in a theater and debating on a Deadpool vs Iron Maiden. Obviously Deadpool's theme fits the theater better. However, I know Iron Maiden is a great game. So can Deadpool compete with Iron Maiden? Which should I buy? How good is Deadpool?
Iron Maiden IMO is one of the best games of all time (yes, I know it's early to say that). A majority of people I talked to loved it within their first few games.
Deadpool seems generally liked, but not loved. I think it's fun. Fantastic sound and art. Easy to understand gameplay.
Earnings wise: it took about 4 months for my Iron Maiden to go from a top earning game down to an average earning game. I'd consider that "fine", but nothing to brag about. I have some games that have gone years earning well above average. Deadpool has only been out for 11 days, but it had a slightly stronger start than Iron Maiden. My guess is that it will take longer than 4 months to flatten out, because it's a stronger theme.
TL;DR If you're buying for the game, get Iron Maiden. If you are buying to earn money, get Deadpool.
