GamerKnights has a done a very in depth review of probably the best stealth game of 2015, "Metal Gear Solid V: The Phantom Pain" on Xbox One/PS4.
"In the open world, you also have a lot of choice as to how you approach each mission. There’s always opportunities for stealth (although this is more difficult than it should be for the first few missions until the sneaking suit is unlocked), or to blast through everyone. And Metal Gear just lets you choose with no penalties, which is incredibly refreshing. There’s no consequences (beyond perhaps missing some side objectives) to worry about, and you can get an S rank regardless, as time spent is a big factor into your final score. "
