I've been to 2 pinball expo's (so not nearly enough to be very knowledgable) and I've had a close eye on the tournament games they used for the big dogs of the pinball world. To me, the games seemed to be games that were fairly common. It seems there's a game from each decade of pinball with the newer games being pretty popular games. Do they choose randomly for the tourney's? Or do they just look at the all the machines at the expo's and pick the ones in the best shape? I think it would be much more impressive to have people playing games they're not familiar with rather then games they've played many times before so that it comes down to true pinball skill. I'm really great at my Genesis machine but that's because most of the shots have become a muscle memory-typed situation since I've played it a lot. Of course you're going to be better on the games you own or have played for hours and hours.
I'd like to see a tournament with 5 or 6 of the hardest machines out there.
And if the games are chosen randomly then I guess that makes me appreciate the players abilities all the more. Just curious though.
