Metal Gear Solid V is not a good game. Kojima hasn't made a good game in years and his writing has devolved and gotten pervy before even 5.
It's an incredible game. It's a shitty story telling vehicle.
No, it's a bad game with a good gameplay. Everything surrounding the gameplay itself is bad. World design, mission design, structure, mission variety,boss battles, story, characters, enemy variety, senerio design, traversal, character progression, and just simply being a Metal Gear Solid game.
But yes when your in a base being stealthy it's ok.
