Keep in mind that a lot of the disappointed have left already.
Are you serious! Quite the opposite, I would rather say that keep in mind that most of the people who love the game have left due to being insulted a lot or being just plain tired of complaining and having better things to do.
But, to the subject (okay, sorry, copied things that I agree with):
Graphics 9/10 - I have it on medium with a 5 year old computer, works wonderous. Some bugs are there though.
Gameplay 9/10 - Once you get past the bugs (no lag for me), it's pretty immersive.
Replay Value 10/10 - I've played so many games now that I've lost count. Immensely more replay value than IV, which is just a big min-max.
Sounds 10/10 - Love the music. Just love it.
Multiplayer 6/10 - Fun, yes, but 1. No good save/load options and 2. Bugs+lag, especially in LAN play.
Price 9/10 - You get a lot of hours of gameplay out of this game, so well worth the money.
DLC price 8/10 - Yes, who wouldn't want everythign to be free, but come on, two civilizations for like the cost of cheese in the food store? (about 4€ or 5$) Is it really that bad?
With regard to the bugs in the game - I remember buying Civ4 when it came out and it was riddled with bugs also, which detracted severely from the game. In fact I would go as far as to say that IV did not become a truly great game until the release of the "Beyond the Sword" expansion pack, an expansion which gamers had to pay for, no less.
Exactly this..
BTW, if you always expect a game to be 10 at release, you will about always be very disappointed, it's not realistic at all. Waiting before release for every game to be 5 would be more realistic.
