Tinker, the game also has a downloadable map editor witch is nice, when you want a different puzzle type game to play on a machine with limited power. Or when you don't feel like playing a big game. But as a Vista Extra... it's disappointing, and sounds and games doesn't really fill the description of Extras. The game should be an added bonus/value attach with other actual extras worth of the money paid.
Also, Dreamscape is NOT a video-based screen saver, it's a video-based wallpaper.
