Summary: Had this game for two years. It was incredibly fun and addictive. I really liked the new vehicles and weapons Rockstar released with the expansion too. I finished both episodes along with the original GTA IV and I must say, I had a blast playing all three. But now, I've moved on to Grand Theft Auto V, and will never forget the epic moments I had with GTA IV and the Episodes of LC. It's definitely a must have for any GTA or Rockstar Fan.
Summary: if you already have GTA 4 it will just add its self on to save data and trophies go right into your GTA 4 . There is online play for TLAD Seems like you get a few new cars, bikes, songs, and other things on the radio, new guns also
