It's easy to forget, but there can be hundreds or even thousands of people involved in creating a AAA video game. There's the obvious stuff, like the writers, producer and lead designers, but there can be dozens of different roles at every stage of development. An overlooked role is that of the concept artist, despite creating hundreds of drawings and paintings that can ultimately shape the artistic direction of the game. Whether it's designing specific outfits, illustrating particular environments or crafting the general aesthetic, concept art is hugely important when it comes to a cohesive look and feel. While not every game turns out to be a big hit, there have some real works of art that have come out of the development concept work. The majority is never officially unveiled to the public, although sometimes publishers will release certain pieces online to build hype, or even use the best works for loading screens or box art. This list celebrates the best of video game concept art, with 33 incredible pieces that deserve to be hung in a gallery. From sci-fi dystopian masterpieces to epic, green landscapes, these works of art rank among gaming's greatest.
