The upcoming NBA Jam reboot wasn't always an NBA Jam game. It was originally called NBA Bounce, and looked very different.
1UP has a gallery of concept art for the title, showing the long creative road the game took from its days as an ad-filled Bounce to the classy NBA Jam remake it is today.
Some of the pics show the game could have gone the fantasy route, while others show it could have been about as interesting as FIFA Street. I like the Lebron concepts the best; especially that one that makes him look like an extra on Peanuts.
There are dozens more shots over at 1UP, so head there to see the lot of them.
