It's true. Bowling is really the only sport of the package that is really a complete game. It could benefit from some depth, but everything is there to kinda bowl 10 frames like you would in real life. Tennis is just swinging, no control whatsoever of your character's movement. Baseball is just swinging. No stealing bases, or even deciding whether to risk a double when you hit first base and see that the ball hasn't been picked up yet. There's no (controllable) hook or slice in golf, and there are only a couple of clubs to choose from. Boxing effectively doesn't even function. But the bowling offers a simple, but basically complete bowling experience.
So it really is funny to see someone come along like this with a dedicated Bowling sim, after seeing how to do it. And make no mistake, reproducing Wii Sports Bowling is not beyond the capabilities of any half-competent developer -- the game is barely more than a tech demo. It's a lane that never changes, with 10 pins, and a single gesture for throwing the ball. The entire bowling portion of Wii Sports was probably completed, start to finish, in well under six months. Probably more like two.
Anyway, yeah, publishers of games like these should be criminally liable for fraud.

The court should apply some sort of "reasonable person" test, where they decide whether a reasonable person who saw the game on the store shelf, having heard nothing about the game prior, would think that it could possibly be that terrible. And Wii Sports Bowling could be entered in as evidence of what a developer can do with bowling on the Wii with almost no time or resources devoted to the project.
