I am in game design and development here in Cali, and I gotta say that the Transformers Movie game isn't all that bad as those game site critics like to say it is. They have an over whelming sense of whats good and whats horrible. Don't mind them, with a few exceptions, I can definitley recommend this game for the Transformers fans. It has full in game transformations, a semi destructible city environment, and yes though story content is lacking, its really all about the playability of your favorite characters.
Most Movie games are lacking, I agree, but you get so much that makes up for story content. I attribute this game to that of "Star Wars Episode One Pod racer", though hardly any story, it was a blast non the less. And the unlockables are sweet!! The cybertron edition has an extra unlockable level where you have a mission on Cybertron, so keep on playing and when you unlock it, you'll see why it's worth it to see the movie rendition of the Cybertronian Home world!!
the DS version and PSP versions are fun as well..
Over all as a Video Game designer, I give it 8 out of 10. Considering the time constraints, because they had to work closely with ILM, and as we know the movie designs kept being revised, and what they gave us, I can live a little without the extra story content.
I mean this is their first landing on our world, the movie and game should be more about the first initial battles and not about the story so much, leave that to the sequels, and game sequels.
