I have TSPP and AFM, but keepers for me but very different.... I really love them both.... and TNA is on my watch list..
Theme: Tie... I love them both:
Appearance: Tie, both nice art packages.
Sound: AFM, sound package is awesome, I think one of the best ever.
Deep code: TSPP all day long...vs. most pins. Good luck getting to the end, I will never see it.
Speed, flow... AFM has the edge here, its a simple fan layout playfield that is just awesome.
More shots.... TSPP, lots of stuff on that playfield, I don't think this game gets near enough credit for playfield design....
Overall: Tie, great to have them both in small collection.
