It appears the final cover art has been released for All-Pro Football 2K8. You can see the full size image by clicking the thumbnails below.
The artistic style of the cover gives it the feel of being from the “past” however there is just something about it that doesn’t click with me. Blitz: The League went a similar route with their covers. I feel like it’s the cartoony look (especially in the case of Elway) that doesn’t come across right. Probably was a good idea to feature a trio as opposed to just one player to give the idea that legends are the focus of the game since the title doesn’t do that on its own.
