Far Cry/Fridge

Fridge Brilliance

 * This isn't mine and all credit goes to the guy who first mentioned it, but I thought it to be relevant: You know all those Goddamned Bats that are endlessly respawning enemies, no matter how many you kill? They represent the futility of trying to change things in Africa. There'll always be another crazy gunman. - User:Gentlemens Dame 883
 * The Jackal acknowledges this in his tapes. He talks about how no matter how many men you kill there will always be another soldier to take their place and be brainwashed by the corrupt forces in power. The futility of it all makes the Jackal consider that killing everyone might be the solution, no people no more wars. Before that he at least acknowledged that maybe if America were willing to dedicate its Military strength Africa might have a chance, but at the end the Jackal has given up all hope of changing the cycle.
 * In English terminology a far cry is an idiom describing how one thing is different from another thing. How does this apply to the Far Cry series? The war torn areas that the protagonists find themselves in are a "far cry" from any sort of peaceful civilization. Far Cry 1? The Island is filled with mercenaries and mutants. Far Cry 2? War torn African nation with criminals, warlords, and mercenaries all over the place. Far Cry 3? Stuck on a remote Island with war lords, insane people like Vaas (Definition of Insanity guy), and your girlfriend has been kidnapped. All of these places are a far cry from civilization.
 * Instincts gets much more fun and satisfying, especially in dark areas, the instant you realize that you are playing the monster terrorizing everyone from the shadows right out of an action-horror movie.

Fridge Logic

 * The diamonds are referred to as being "rough" diamonds, and while they certainly have the foggy, milky appearance of an unpolished stone, their shape still resembles one of the typical diamond cuts (sort of like a chaos emerald, you know). Coconut Effect, most likely.
 * Your character seems to have an unlimited supply of matches with which to cauterize wounds, but when you're out of Molotovs and flamethrower gas, can you use those matches to start fires? Of course not!
