I would be really surprised to see any review less than 4 stars.
I'm not sure on what basis it's not, at least, a 4 star game. I'd really want to know how a reviewer could justify less than 4 stars.
Sometimes this forum sounds too much like the zealots at Civfanatics. It's a real turn off.
Most of us that have played the game and supported StarDock have seen how far this game has come since WoM and are basing our assumptions of "nothing less than a 4 star game" on the amount of improvement between FE and WoM and not of the game itself. I can easily imagine reviewers looking at FE and saying things like, "No siege battles, no multiplayer, tactical combat not fleshed out, balancing still needs a little work, seems like the game components aren't gelled together yet... after some updates and expansions this could be a great game. StarDock has come a long way from WoM but is still running down the home stretch before the finish line. I give it 3.5/5 stars."
Reviewers today I think put too much emphasis on how easy the game is to get into. Niche games with steep learning curves? Dominions 3 - 82, Distant Worlds - 78. SotS Prime never got above a 79 even with the expansions (Prime -68, BoB - 79, MoC - 75). All of those games I consider to be strategy classics worthy of space on anybody's HDD... yet only Dom3 cleared the 80 Metacritic bar by a measley two points. FE should get around an 85, but I will not be surprised to see it hovering around 75-79.
