If there's an exact opposite to the game Dead Space, it's Flower. Aside from the fact that I enjoyed both of them, and that they both look beautiful, they couldn't be more different.
You start each level with a single flower petal, and you control the wind to blow the petal into other yet-to-bloom flowers, causing them to bloom. Each time a flower blooms, you pick up another petal. As shown in the picture at right, you eventually have a stream of petals following the original one, making it easier to bloom large patches of flowers as you swoop across the countryside. As you progress through the stages, you get closer to a rundown city, and the weather gets progressively worse. Basically, your ultimate goal is to revitalize the city by making flowers bloom.
The graphics aren't groundbreaking, but they're still very good, and the pretty scenery alone is worth playing the game. The music is simple and soothing in the first level, beginning with a solo guitar (think "Brokeback Mountain soundtrack") for both music and sound effects, and in later levels, the music will build, as other instruments are introduced. I know it seems rather... pleasant (O.K., boring) for a video game, but it's actually a fun game, and it's nice to see something so completely different turn out to be interesting. It's not very long, nor is it very difficult, but it's only $10.00 (Playstation Store download).
Not that I'll be giving up my M-rated games anytime soon, but Flower is a welcome diversion. If you own a PS3, I recommend it.
