Reality Fighters (PS Vita Game)
Now new gadgets, add-ons, and systems there is usually a gimmicky title that comes with it early on that makes use of the new and unique features available on the platform. With the Wii it was Wii Sports, the PS Move had stuff like Kung-Fu Riders (which I heard was horrible), and the DS had a demo of Metroid Prime Hunters which had you using the touchscreen to aim.
The PS Vita has a mix of features found in a lot of portable devices today, the one being used for the game Reality Fighters is the cameras. Reality Fighters is a fighting game where you create you own custom fighter and fight some other random created fighter. The thing is you can use the camera to take a picture of yourself and have the game generate your face on the character. Sounds cool and has your standard fare of gimmickry right? But wait, there's more. You also use the rear camera to capture a video stream of whatever is infront of you to use as the background arena for the fighters. The game looks fun and goofy. Perfect for when you're out and about and want to kill a few minutes by just beating the crap out of someone while using whatever you want as a background.
