The gamespot review is much more "fair" to the game than the IGN one imho, although they mostly end up with a similar score (the reviewer do stress the stonger points of the game, despite beeing irritated by the weaker points).
I guess it is just a matter of perspective ... If the films did not exist, how would one judge the Lord of the Rings books nowadays ? A deep, immersive and epic adventure, depicting a living and detailed imaginary word, but unfortunately, the story is way too long, there are too many secondary characters, the storyline is too complex, the author spend too much time dealing with useless hobbits in the Shire (horrible "reading curve" ! where is the action, where are the orcs ?), and those interface issues (I mean, olde english, not to mention elven language and poems, come on, just use plain english, its so passe ...) !
Okay that was an exagerated bit of irony

(and the critisisms against Dom2 interface and learning curve are valid, not my faked critisism against Tolkien's masterpiece) but it's just to show that the reviews are kind of missing the point. Yes, the game has flaws (it's an independant game made by two passionate gamers, after all, many seem to forget it), but it's not the point. It's a classic. The question is how lower can small (heck, even large

) details bring the score of a classic ?
It's all about the difficulty of judging a game (and I am not blaming those reviewers here). Example : at this time, I am playing essentially two games : dominions 2 and spellforce. Spellforce is a game I enjoy a lot : superb graphics, interesting storyline, immersive blend of RTS and adventure game (and it comes with all the crunchy bits too : a good tutorial, a nice UI ...). However it has a quite large flaw : neither the "RPG" nor the "RTS" part are deep, and up par with other games. Despite this flaw, I am just enjoying a lot, and it is definitely worth buying and playing.
So, how would I give a score to both games ? For dominions2, I would say that the game is incredibly deep, rich, with tons of options and strategy, but unfortunately, the note will be brought down by interface and tutorial issues. For spellforce, I would say that the game offer rich graphics, a great interface, an enjoyable blend of RTS and RPG, but the note will not be a perfect one, because, in the end, neither the RPG not the adventure part are completely satisfying and rich.
So, if all factors were considered equally, we'd have both games, with an overall positive impression, definitely worth buying/playing, but with some (not minor) issues that prevent them from beeing flawless. So, I would probably give them the same score.
Not.
As much as I enjoy playing spellforce at the moment, it doesn't take rocket science to figure out that one of the game will be shelved when the campaign is done, with the warm and fuzzy impression of money well spent, but that's all. The other game, otoh, will probably remain forever on the hard disk, will probably lead to hundred and hundred of hours of future playing time, and will be remembered for years (like I remember the hours playing MoM, civ1 ...).
One of the games is a good game, the other one is a classic.
So, despite the flaws, despite the interface, despite the lack of tutorial, what score does dom 2 really deserve ?
