Took the time to watch a couple of reviews. A couple of thoughts about these reviews, as an operator and owner, game reliability is an important part of ownership. Ease of maintenance and number of repairs after a certain amount of plays. The fact that Iron Maiden has service rails instead of pegs on the Pro is worth mentioning, maybe I missed it? Something to consider in future reviews.
Other thought, and this is regarding the Guardians review. How anyone could rate Guardians .73 code at anything above an F, considering that D is still a passing grade is beyond me. That sort of grade just kills your credibility. Thankfully, Guardians current code is making the game much more enjoyable.
