As a gameplay package Episodes from Liberty City offers literally over 20 hours of a superb GTA experience for a budget price. It has been put together to save people the trouble of making room on the ridiculously expensive Xbox 360 hard drives - however thanks to poor optimisation it might be the kind of title you install to your HDD. You only need to parachute and crater into a billboard which only existed after you died once before you come to this conclusion. If you traded in your copy of GTA IV or you are indeed rocking a smaller hard drive, absolutely get Episodes from Liberty City. Otherwise, maybe pick up Ballad on the Xbox Live Marketplace.
