Well, I played through the Campaign too. Here's my Review...
The campaign itself is very good, also, the Maker really knows about how to make Missions interesting and how things can be put together.
One or maybe two Missions were a little...confusing...At least the first time. Someone new to the campaign should definitely play it more then one time through...Otherwise, you might get a little unsure about everything. But that isn't really negative, you know. Making a Player focus on one campaign is quite a talent.
The story itself was good, allthough I admit, firstly, when I read the description in this Thread, I thought, it'd be more a boring and more of a standard Campaign. But it wasn't. It wasn't at all.
Everybody, who's tired of Transcend or Sync and want something new to play should check this out.
P.S.: The Music was wonderful, as I think.
