Quoted from atrainn:
I went pro on Deadpool mostly because I just don't see much improvement in the premium. There are a couple of things I thought were neat, but not enough to make me go for premium. Maiden on the other hand I think premium is hands down the best version and worth the cost. Either way, with most of these games if you won't miss the money then you might as well go premium haha.
I agree with you that Iron Maiden Premium is the better of the two, but unlike Deadpool it's not a 100% perfect recommendation and comes more down to user preference because the Premium plays much differently than the Pro because the mummy lock shots are moved on the premium to the ramp. So on Maiden, I can see someone preferring the Pro and I would totally understand why. But there's no such ambiguity with Deadpool. The Premium/LE is the best experience.
