It is the opposite in my house. Linsey will destroy me on pretty much every game. If I did have a chance at beating her and I threw the, game she would have my head.
About the only games I can come close to her on are older machines with no initials.
I dislike that some games you can get all the way to the wizard mode and still not beat a GC. That is what I find frustrating about a lot of newer games. Shot, mode, and playfield multipliers are king. I don't care to look that stuff up so I know I don't have a real shit to ever take her scores down. Especially on JJP Pirates.
If she wants to see more of the game that is cool, but doing so doesn't necessarily mean she will get a GC. If she wants high scores, unfortunately she may have to find some tourney strats and stick to the same modes over and over.
