While i enjoy large open world games, breakpoint has taken it one step too far (not that surprising with this game). No GPS makes it too hard to drive on roads (without going to map every few seconds), steep cliffs make it too hard to walk/run, and when your in a helicopter apparently you see nothing of the world according to the map/world discovery stat even though you can find out what sites your above.
I mostly choose to fly or walk, to missions and flying was frustrating especially with the helicopter controls and as i've mentioned above walking was a pain due to sharp vertical climbs meaning getting to missions took stupid amounts of time.
All of which takes from the game rather than add to it.
