They really don't get the whole thing,
Demigod is essentially a multiplayer game, that right now has connectivity problems that are known and are getting fixed.
Its like saying team fortress 2 sucks for the lack of single-player, thats totally bullshit.
The review is unfair, only one part of the game is not working, if you look at the whole thing youll see that demigod is unique.
I agree with you and I'd like to state when does GameSpot ever fairly or view a game as a nonbiased reviewer (maybe when cash is passed, or I should say when its not and bad scores are given). This can be the same for any adventure game that goes through GameSpot or PCGamer (some of the worst ever reviews), its guaranteed to get stupid jokes like where is the dragons to kill (the PCGamer URU review), but you get my point. They always seem to send in reviewers that hate or don't even know what to look for in a particular genre of a game and give it the worst feedback they can think of. Why have a FPS braindead reviewer who likes to point and shoot only review something he never plays? Its a guarantee that he's going to score it low and be way off on what the game is really, or did he even really play it? This results in other people that actually take those reviews and base a decision on making a purchase or not, hurting sales and sometimes companies making their last game.
I don't even visit GameSpot, IGN, GameSpy and a couple others do to this fact. Noobtoob guys, even though they are not really that funny or entertaining to watch, they do usually have an open mind to whats being reviewed. Still they are a little biased at times and it does show in some of the reviews but nothing like the 3 mentioned above with scores out of wack. I still remember reading PCGamer reviewing a game I really enjoyed (Aura, I like adventure and rpg games) and he goes on saying, what is all this useless junk in this room and what the hell am I supposed to do with it. He continues on like this and gives it an extremely low score (under 10% I believe it was). Well adventure games are made to figure things out, solve puzzles, explore new worlds etc... he couldn't grasp this concept. Then you check out an adventure gaming site and they will have an completely opposite score.
I'd just ignore those sites and wait till things are running smooth and then see the true reviews start to popup.
