Well the game seems fun, I've started my first playthrough on normal with hardcore mode. Because the game has iron sights I am playing the game with crosshairs off. Shooting with no crosshairs is easier than it sounds, I've managed to figure out where the bullets might travel with out iron sights. Not only that but with out crosshairs the game seems more realistic. Obviously if a giant scorpion were charging at you your movement would be more jerky and inaccurate and you probably wouldn't be able to aim that well.
Oh and it reminds me more of Fallout 1 and 2 which is a plus.
