From a story telling perspective this looks amazing. From a gameplay perspective: meh! It's not amazing but it'll do.
I'm not happy that Bumblebee's gone mute again. The fact we haven't had confirmation of a FoC figure for him yet and the rather ominous first trailer makes me wonder if 'Bee will be spending a lot of this game on the bench.
The voice work doesn't convince me. The actors have done a great job but the sound guys have just copied 'n' pasted them into the game. There's no sense of atmosphere or spacial positioning apart from that moment when Bumblebee's been knocked on his ass.
The way I view any continuity issues is the novels are the novels; the games are the games; the PRIME animation is the PRIME animation. They're all telling the same story (with PRIME many millennia ahead) but they're in alternate realities where minor event has played out differently.
But then that doesn't explain 'Bee's lack of voice.
