If you're a good player, the pro is probably a better option, as you can't cheat your way through all the modes on the upper playfield.
If you're more into an impressive looking game with "all the stuff," GOT pro is one of the more lackluster Stern machines in recent memory. Carbon copy Steve Ritchie five-shot layout that he can design in his sleep.
Dwight's code really saves this one for me. So much replayability with all the different houses to choose from. Okay, you beat the game, cool. Now try it with all the other houses. Different scoring approaches with each house as well.
