CrossEyed, that's the point where you get into things like people liking particular artists and such. Like how I recommended the Devil Survivor games to a friend because the art for the games was done by the same person who did the art for an anime she liked.
...but yes, the Japanese cover for WarTech is pretty generic as well. It'd still stand out better over here than the box art we got, though. (In reality, it doesn't matter what the box art looks like for the Japanese version, because it's an Xbox 360 game and therefore no one was going to buy it in the first place. The Xbox 360 being a "filthy gaijin" game system and all.)
A better example for what I'm talking about - which in this case would be people liking artists and American covers being terrible - would be Atelier Rorona. The Japanese box had the title of the game and the title character standing in a town. Now, I really like the art for the current iterations of that series, so I'd probably buy that if I saw it and had a PS3...on the other hand, the US box has the title of the game and a wand. They removed the main character from the cover of the game because, again, retailers won't carry anime games.
Also, the more he posts on this subject, the more ShadowBrian sounds like one of those people who hates on Angry Birds because it's a popular game on a cell phone and therefore THE DEATH OF TRADITIONAL GAMING, despite it being little more than a traditional puzzle game with a neat aesthetic and a low price tag that happens to be available primarily for mobile devices.
