Hard but enjoyable
This game is quite good looking for starters, if you ever get a moment to just stop and look at the world around you you will see what I mean. But the point is you probably won't, for you will be too busy fighting the enemy AI that is located in every part of the map from the deserts to the forests. If there was a leveling system this wouldn't be a problem, however the only thing there is to reward you with is gems which you yourself with your GPS, which in turn you will have to use to buy ammo for the ones you used killing the camp. But the fun doesn't stop there, it's not like there are weapon merchants everywhere, no you have to one and along the way guess what you'll find....you guessed it, more AI which are not just pushovers.
Now you may be thinking to yourself "why not just run past them?". The reason is because you can't, because they have access to vehicles just like you do, and it is apparent that it is their life goal is to hunt you down and kill you chasing you half way around the map until you get to a safe zone. Now you may be thinking to yourself "Well for all that trouble this game must have a pretty sweet story line?" Wrong again. This games story line never feels quite complete, and even at the end you will feel disappointed.
However after nailing this game for 2 paragraphs it's only fair for me to tell you what makes it worth playing. The combat is fun, their isn't an RPG out there that will make stalking out enemies and debating how to kill them so enjoyable, whether it's with sniping those people in the watch tower, lighting the ground on fire to burn nearby enemies causing the rest to group for that perfect grenade spot, or even shooting an RPG at their trucks stationed so you can run over all of them.
The other great thing about this game combined with fantastic combat is how great this open world feels, some missions will require you to travel down the same roads but you will never find yourself complaining about it because the world is beautiful and makes you feel apart of it. Whether it's a tree in the distance or an explosion you will notice how well made everything is.
