I don't know how long reviews usually take to land, but I agree it is starting to smell a little funny. I mean, Stardock spent their dough on developing this game, not a marketing scheme. I would think that that would not make it ineligible for professional reviews. I see sites like Rock Paper Shotgun review indie games all the time with real good heart as well, so where's FE?
I have two theories, although they are just trains of thought more than something I fiercely believe.
First, I think reviewers are holding back to see what other reviewers are saying. With E:wom in the past, they are unsure how to treat FE. Maybe they don't want to stand out, be "that guy" that perhaps gave a really bad game a great review, or a really good game a really bad review?
Second, I _hope_ reviewers started playing it and find themselves lost in the content the game offers (as in - they feel they have to play through scenarios and sandbox to give a proper review).
It is also possible that they follow some kind of review schedule, basically "feeding the websites" with a certain number of reviews every week. They'd do this to keep interest in the website even. So if there's a week where lots of good games come out, they spread the reviews over the next month if they're in for a cold patch.
