It does kinda remind me of the older video games we used to like to play (well actually I admit I still play them). Stuff like Doom, Quake, Duke Nukem along with the console games like Zelda, Goldeneye and such. None of these came with any walkthroughs in the manual, just a description of how the controls worked and some info on the characters. Before the Internet got big, typically not long after the game came out you could buy a book that was a complete guide. It would have maps, strategies, and everything you needed to complete the game.
I did often get these books. But I hated using them. I only would go to it if I was completely stuck at a certain point and couldn't get out of it. Then I would peek so I could keep going, but I always felt like a wuss when I did this. But I knew lots of people who would just go through the book from the beginning to the end using it as a guide to get them through. I didn't like that, but they were happy. People are just different that's all, no big deal.
These games often had various cheat codes and god modes. You could type in a code and get extra weapons, power, etc. I knew people that would enable god mode that gave them unlimited weapons and ammo along with invulnerability and they would just plow through the game that way. They were happy as clams. I never used those cheats myself, for me it just took all the fun out of it.
For me pinball would be the same way. I'd like to try to figure it all out on my own. But if there were a nice rule set to look at if I got stuck, I'd like to have it. Of course now you have the Internet so you could just come to a place like this and ask and get your answer that way.
