Yeah, I can see where you're coming from. I like to look at the game and only the game when deciding anything about it. If there were any preference based on background, or any judgments made based on the background of the developer, the review is just not as good as it could be. It really is about the game, and not necessarily the company. Again, looking at it that way, it's a mediocre game that didn't work on launch and has completely unnecessary DRM and auction house systems that detract from what the game encourages by design. It certainly gets a failing grade... but it functions. It's a game you can play. It's a game that some few people actually enjoy.
...actually, this is what makes reviews more useless. We're defining separate meanings for what '0' means. The numbers don't really mean anything, because 10 can range from 'pretty great' to 'perfect in every way'. Likewise, my hypothetical definition of 0 is a game that is a complete failure in every respect... meaning that you can't even call it mediocre. It cannot be played, it does not have a story, or gameplay, or controls that work, or any other critical part of a game. All aspects of it are broken beyond belief. There are no redeeming qualities. Diablo 3 does have redeeming qualities. It's a game that I actually can wish was better, because there was something there. It's just that it was fundamentally flawed out the gate with the DRM and AHs and stuff.
