To be truly unbiased, a publication has to be impartial with every review, regardless of system, regardless of developer. I think we can all agree that this is correct? Assuming that we can, an interesting argument arises regarding Edge's take on the games this generation. To please all devout single console owners/fans, are we suggesting that the mean (as in the average, not as in 'Scrooge McEdge only gave MAG a 6!!') scores for Wii, PS3 and 360 games should sit level with each other on a graph? Nonsense. Perhaps the varying review scores for console exclusives merely confirm Edge's impartiality? Maybe the 360 has actually shaded it so far this generation, impartially speaking? The LittleBigPlanet score shows that Edge has no problem awarding a perfect score to a Playstation game. See also Super Mario Galaxy. See also Halo 3. The fact that the test platform for multiplatform releases is often the 360 merely reflects the state of play - that cross-platform releases are still more often than not superior on 360, and Edge opts to review the (however marginally) preferrable title. Is that such a heinous crime? I'd imagine Edge's core readership is a fair bit older that that of, say, IGN, and I'd also suggest that more of its readers own multiple consoles. I own the PS3 and 360, and I have two rules for buying multiplatform titles. 1. If a game is vastly superior on one machine, I'll buy the superior game (Bayonetta 360). 2. If a game is of similar quality on both machines, and isn't a FPS (I prefer the 360 analogue pad), I'll buy it on the PS3 in case my 360 blows up whilst playing it. Simples.
Do I agree with every review Edge prints? Not even close. Recently, NSMB Wii stands out as a title that deserved a higher mark. Killzone 2, imo, did not. Bayonetta could've done with a point shaved off. Bioshock is what I always considered an 'Edge 9'. You can't agree with any publication more than most of the time, and this has been true since I started buying The S Mag in the 1990.
Going back to my initial sentence, I sometimes wonder if Edge is a little loved-up with Rockstar and Valve. I used to hate the magazine during the Megadrive days for similar reasons the OP does this generation. Like Retrokings1981, I think their Let's Tap review was nothing short of ridiculous (probably my biggest Edge WTF since the Gunstar Heroes review). They used to slate the first Lord of the Rings film, adopting the 'royal we', as if each staff member agreed that it was hammy and overblown - I think one month they asked people to stop writing letters about it (I haven't forgotten this haha). I raised both eyebrows when they ran their GTAIII review, and attached a score of 6 at the foot of the page, which, after other publications marked it highly, was retracted in the subsequent issue, labelled a typo and changed to an 8 (a game they've listed as the second most important of the decade in this month's issue, btw). Edge is not infallible. Edge is not perfect in my eyes, but it's still a great magazine, and still head and shoulders above the competition.
