Quoted from vid1900:I like to think of the code on TZ.
The old code was boring, and I could never really get into the game.
It took 7 years to actually be rewritten to the code you and I love.
What are you talking about? Even prototype TZ code had all the game's elements and was fully playable. Nothing significantly changed thru updates - some small features were added (super robot ramp) and lots of polish, but it was still the same game. Nothing like Stern where the rules can change dramatically during game development. I played proto code in TZ for months before getting it upgraded and it was fine. The attract mode "painting the playfield" top to bottom was mesmerizing
