Sorry about the delay in getting back to you all; I meant to write something up a couple of days ago, but the conversation with other editors went on longer than expected. Volunteer work, different timezones, etc etc. These things are not solely my decision, but happily I was able to show people what the issue was.

I personally will be re-reviewing the game. This review will stay up, because nobody likes it when things disappear miraculously from the internet. Please keep in mind that 1. I am busy with other reviews and non-volunteer work and 2. as most of you have pointed out, this is a 4X game that requires a lot of time and detail to properly review. It’ll happen, though, and hopefully soon.

That's the last comment on the review's thread (most of them are people who are pissed).  So I'd expect that number to at least shrug up to a 7 whenever this guy's review comes in (if ever).  Basically, it looks like this site made the mistake of pairing an RPG reviewer with a TBS game.  The predictable result was that the reviewer had little frame of reference and ended up completely befuddled by the game.

Also from the review...

Move a second unit and now both of them attack in tandem, using up the first unit’s turn only. Order a soldier to attack an enemy and everyone beside that enemy will attack.

new players do not understand how the swarm mechanic works.  They see the animation and assume that all the surrounding units all get an attack, rather than that the attacking unit gets a slight buff.

Whoever you have doing your press packets needs to get in touch with reviewers and make it clear how swarm works.  It is a cool mechanic and you're right to highlight it.  (Rushing in with your most powerful units is now a great way to die, mobbing one unit to get the swarm bonus means putting your units in places they will be swarmed themselves, wolves, with their bonus to swarm, are really awesome in packs but weak individually...)  But if the reviewers don't describe it properly it makes it sound cheesy and lame.
