Quick pick-up-and-play fun.
If you were to set Art Style: Orbient, Pinball, and a side-scrolling shoot-‘em-up on a collision course, the result would be StarDrone Extreme. It's an odd combination, yes, but one that frequently provides some quick thrills. However, like Plants vs. Zombies, StarDrone Extreme seems to suffer from being on the wrong platform. While fun in short bursts, the experience fails to engage for more than a level or two at a time.
