To be honest, I don't think that the drilling thing would be as tough as it might appear. You could give the player the option of just going with default drillings/reactions, or you could give them the option to customize their equipment. If they choose to customize, simply have a display page that shows the various drilling options and the reactions that go along with them, just like drill sheets do for us now. If manufacturers allow their balls to be used then there should be no reason why they would object to having the drill sheets for each ball put into the game as well. As for the game play, the makers could make the reaction brought about by each drilling the same for each ball, regardless of company and technology of the ball itself. For instance, in general terms, label is going to go long with strong backend, stacks are going to roll a bit earlier with some good pop on the backs, Pin axis will be tame, etc. I don't know how to develop a game, so I admit to ignorance, but it wouldn't seem to be that hard, especiall with how detailed all of the games are these days. I've been wanting EA Sports to put out a PBA Tour game for years. With all of the attention to detail that they are known for, that would be incredible!

Bowling is without a doubt the dumbest, most pointless, most idiotic excuse for a game that has ever been invented. So, what time are we bowling tomorrow?
