You may need to buy it if the load times are that long. If you rent it you'll spend half the time on the loading menu!!!
I have GameFly, so I can keep it as long as I want.
I am sure it will be patched in the future to hopefully drastically cut down load times, they did so with 3D Dot Game Heroes by adding the optional install. Even though this game already has it I hope they figure out a solution because this game looks like pure gold otherwise and I would hate for the absolutely bat shit crazy insane bullshit loading times to prevent me from purchasing it.
iPhone = Great gaming device. Don't agree? Who cares, because you're wrong.
