You're kidding, right? You kinda have to translate anything to CGI for a video game. That's like complaining that you have to turn the Muppets into Pixels for an 8 bit game. You're also essentially complaining about video games being video games. Sorry, but I don't get it.The problem with Muppet Video Games is that by translating it to a CGI medium, you inevitably lose the charm of the Muppets in the first place. You lose the life-like behaviour and spontaneity of the performers, things become very rigid and task based, and it misses the spirit of what the Muppets are and what they represent.
As opposed to every other Muppet video game made under Henson?Right now with the positive promotion that the Muppets are getting, I can't help but think a poorly made game would be detrimental to the brand as a whole, as a poorly made game might reinforce the belief that The Muppets are nothing but Disney's corporate puppets.
The collection of minigames goes back even further than you think... the first Muppets video game, Pigs in Space for Atari, was essentially Muppet based hacks of 3 Atari ports. In fact, out of the history of all Muppet games, the one thing that stands out is the Once Upon a Monster Kinect game which, shockingly enough, is the opposite of everything you said. And it's amazing.
A good, engaging video game is possible, and I'm sure Disney is racking its brain trying to come up with something (why we didn't get a The Muppets game tie in from the same company that somehow made Hanna Montana one).
