Yes, but what you define as a bug might not be what they define as a bug, let's not forget.
The least impressive review I've read - The Escapist - is interesting: It's reviewed without the campaign.
Frankly, I find it stupid that a game can be released - or a film or album - and an official review of that release can get away with "this review copy of such-and-such didn't have yada-yada". It's like reviewing an album with three songs missing, a film without the last third....
Given that, it's hard to take any reviews - whether positive or negative - too seriously, because they're starting from different point.
I wonder how well GalCiv3 would be being received if Stardock had put out a press release on Release Date: Here it is, folks. Galactic Civilizations III!!! Finished. Done. No updates. No DLCs. No Expansions. Any complaints? We'll include some of 'em in GalCiv4." In other words, there's an acceptance that while a reviewer would like to see a certain thing, they're giving Stardock leeway for including that in the future.
