Spec Ops: The Line was pretty good but the white phosphorous scene felt a little forced to me. Like, you have to use the war crimes weapon on a group that as a player you're thinking "nah I could probably sneak/shoot through that" and the game doesn't let you make the choice of not massacring civilians. For most of the game when you do something awful, you the player are doing it because you have John SpecOps's warped perspective, but then the game gives a big "do an obvious war crime" button and forces you to push it to proceed.
They gave the concept a good try though.
Back in my day we had two Germanies and one Soviet Union, and that's the way we liked it!
