Should i buy minecraft for xbox 360?

Minecraft on the XBOX has better Framerate
Minecraft on the PS3 Holds 30 Frames

Yes. It's a very fun game especially if you like to be creative. There's endless things to do on there so you're never bored, at I'm not. Different game play options allow it to get even more fun such as creative or survival mode. I would definetly give it a try as its also pretty cheap.
