Indeed, offering reviews is a service those sites provide to their readers. If, for some reason or another, they don't review a product, I will visit some other site that does.
I know this is wildly off-topic (there was actually a thread about the banning of the ZD network a while back where I was on the other side of the fence
) so maybe a mod would like to split?
Anyway, I think ernst's comment is a good example about what is
wrong with the gaming media. What if Ubisoft banned every outlet that didn't guarantee an 8 out of 10 or better? Would we then
only read the good reviews? Or would we rely on gaming sites to pony up for their own content, while taking a massive loss in hits (ie, greatly reduced revenue) since they'll be far, far late in their reviews (days/weeks after release) whilst not having previews, etc.
There has been a lot of discussion about this issue on GFW Radio - obviously they're on the ZD side rather than the Ubi side - however the key issue they raise is that in gaming journalism what matters is who is
first, rather than who is
best. Take a look at the Haze reviews from small sites, or Sony-exclusive print magazines and whatnot. It is seen time and time again (probably very apt to mention the Assassin's Creed's 9's in exclusive reviews vs 7's in "other" reviews much later). Print mags suffer this greatly given the lag time between review and print. The second part of this comes from the reward for exclusivity - advertising dollars, and potentially the influence on the score. Look at Gerstmann getting fired for a review he wrote about a majorly hyped, yet shitty game on Gamespot.
Anyway, I feel bad for the 1Up guys, because they're effectively being looked down on by forumites who effectively are saying "so buy your own games" without necessarily taking into account the full scenario.
