Take a look at your game collection, notice anything peculiar? Odds are you don't because we barely give cover art a second thought nowadays, but if you look carefully you can see that a couple of designs seem to dominate a majority of covers on shelves. Of course we don't mean the exact covers, but repeated themes and design elements can be found on an alarming majority of boxes.
Now, these designs aren't inherently bad, they just lack the design creativity to separate themselves, but then again that could be part of the point. Marketers put a lot of effort into finding the most visually appealing cover art for their products so you wind up buying them; it's quite possible a whole bunch of them decided a few common traits were necessary for success.
Still, it's an interesting thing to examine. This list only covers a handful of the most obvious ones and a few of the guilty titles, but there are plenty more that could be revealed. Take a look at them and examine the design elements, chances are you won't be able to look at your game shelf the same again.
