I played a prototype (no art; minimal code) of TNA at Southern Fried Gameroom Expo in Atlanta in June. I know that you're looking for people who have *not* enjoyed playing it. Sorry, can't help you there -- I liked it! Thought is was fun and fast. Surprisingly so, because this game has only ONE pop bumper and has NO ramps or other major "toys." But it does have a third flipper, a spinner, an interesting division of the playfield into two major sections, and a very cool ball-lock feature using drop targets. Plus kick-ass music and sounds effects.

One word of caution is lastability in a small collection. I think an owner could tire of the game fairly quickly if the owner had no other pinballs or only one other pinball for variety. But even in a collection of only two or three other modern games, this one ought to hold its own. And, interestingly, it can fill the more "old fashioned" playfield niche that a collector usually has to turn to very old games to get, but can get from this machine on a brand-new basis.
