@Mirefox: 176,296,224. I'll probably just leave it there; Sorcerer is not my favorite.
Sidebar: We could consider the no-extra-balls rule that's used in physical tournaments.
I'm not sure if any of you guys have ever played/watched a real-life event, but many of the players are good enough to basically earn an extra ball every time ... making the events, in theory, endless. So they just let any extra balls drain; they don't even put their hands on the flippers.
I bring it up because even my paltry score above probably took 20 minutes, and I earned an extra on balls 2 and 3. I'm guessing the billion-plus score above had to have been more than a half an hour. Are we venturing into the territory where this becomes more of endurance contest than anything else?
Of course, Sorcerer is not a hard table, and the real tables in Pinball Arcade are more stingy with extra balls. So maybe it's not even going to be an issue. But I thought I'd toss it out there.
