Just finished Metal Gear Solid 5: Ground Zeroes with a GS of 700. While short, I had a lot of fun with it. All the different side missions gave me lots of reasons to fully explore the small play area and now I'm really anticipating Phantom Pain.
The only thing I didn't like was Kiefer Sutherland as the voice of Snake. Snake's had a distinct voice for nearly twenty years, so whenever he speaks it's jarring. Was this a role that really needed a Hollywood actor? I'm sure David Hayter would have came back (for cheaper than they paid Sutherland I'm sure) and gladly reprised the role.
