Yes, Cindy! I liked the KP one because not only was that my favorite show back in the day, but it actually was kind of interesting. The thing about KP that makes it tick both on the show and at the game is that it's not one villain, it's multiple villains with different personalities with different schemes. Plus those villains are wayyyyyy better than Dr. Doofensmritz. The Perry one bored me very easily, just to be quite honest. I do not like the Perry version at all. They probably changed it because KP is off the air and I heard that nobody knew who she was, so they changed it to Perry so more people knew what was going on in the game.
I have no clue if this is true, which it probably isn't. Another thing about the KP one was that it had all the characters you liked in it, as they didn't have a ridiculous sub plot in the game like Perry does. In this game version, the boys are off building some whosewhatsits that are supposed to "help" you. I personally think that it was a little too much like you are interacting with the show. I also this the KP one was better because again the villains actually had evil plans that made sense, as Dr. Doofensmritiz quite frankly still has no motive or real plan.
This is my opinion, you do not have to agree with it. All I'm saying is that the game now is not as good as KP was. Perry is just fine, but it feels like I am watching the show instead of playing a game. People really like it, but I just think it's a little boring because it's reacting the exact same predictable thing that goes on every show. Once again, this is my personal opinion so you don't have to agree with it.
