TZ i always avoided on route, hell you can even look back at some of my posts on pinside for my thoughts on TZ, but a nice example fell in my lap, and now i totally get TZ. So many ways you can attack this game, and stacking the different modes and how the powerball can interact with them is really a treat.
TRON was another pin, when i first played it and didnt know the rules, seemed meh. I was aiming for the ramps, and nothing of note was happening, seemed like the only way to advance in the game was CLU or the disc. I have totally different feeling about this pin now, and will own one day
