FO3 and NV? Hardly ever used grenades but mines were my best friend. My very best friends. I could not get enough mines. Frag mines, plasma mines, bottlecap mines, I welcomed them all to the party. Oh the traps I laid and the carnage wrought with little to no gunplay. Good times. Good times.
Looking forward to the change with FO4 and the hotkey. I've always believed you could have the best of both worlds with FO. The skill level determines random critical chance, critical damage, and damage. The player skill determines if you hit or not. I just hope the default game does not have some weird bullet climb like the arrows in Skyrim.
