I think they know how to code otherwise there would be no game. The issue is the code density across the game. Red Dead Redemption 1 and 2, gtaV, gta 4, Mafia 2 and 3 Skyrim , ALL ASSASSINS CREED, modern Far Cry games etc dont have the graphics or code density of this game. Thats like saying that everyone that knows how to climb a tree should be able to climb a mountain. This is the mountain of games with the tech involved and you're talking trees. Sigh....
