Fulton simulator.
Really though the gameplay is fantastic. But even that can be picked apart to shit. You build MB, for what? Fulton soldiers, for what? You have hundreds of weapons, how many will most people use? I play mostly stealth no kill, so I haven't even touched 90% of the weapons. The intros and outros of every mission, being dropped off by a helicopter ever damn fucking time even when you want to clear side ops, or you can run or ride across a big ass, boring map. Cover system is mediocre since it's pretty touchy. Sandstorms are more annoying than useful. All that time spent in menus, sending soldiers out on missions is as pointless as sending out Assassins in AC games. In fact, this is an Assassins Creed game, without the good climbing mechanics since its hit or miss on what you can climb on, what you can't and when Snake will decide to slide down a 2 foot boulder. Instead of collecting shanty songs and feathers you collect soldiers and blueprints, cars and tanks. Waiting for shit to develop in fucking game time, give me a break. This is just a bigger, prettier Peace Walker with a shittier story and worse boss battles. Miller ever flaps his gums in your ear all the time, just like PW.
