Games based on movies generally don't have a high quality reputation (as told to me by my PS3 addicted partner). I guess they think the brand moves the product enough already so why make it shine? Sad, really. I hope the game is good.
Well, the game looks to be like a DDR type deal, only with the controller instead of a mat (or Guitar Hero without the guitar). Sort of like the Japanese video game Pop N Music (
example Sorry, I picked out the one I liked the most). But clearly with Chipmunk imagery (and probably chipmunk music).
But movie based games fall into "just merchandise." I mean, even in the old days. Of course, there are some good ones of note. The Genesis version of Aladdin had some great 2-D animation (the SNES one was different, but quite fun in its own right). And the 16 bit Toy Story games had a nice CGI animation feel to them, which sadly was lost in TS2, for PS1.
And even in the early days, stinkers abounded. LJN had NO RIGHT to make video games. they were frustraiting, bad, and had little to do with the films they were based on. i'm sure you'd remember Roger Rabbit for NES, Frogboy. That one was a real stinker, as were both back to the Future games.
Kinda disappointed they made a game instead of (at least) T-shirts.
