I preferred the bow for most of the game. My loadout was usually Bow, Shotgun, Rifle and Sniper. Shotgun is hilarious when fully upgraded, Rifle just has an absurd amount of laser ammo, and the Sniper had fucking semi-auto explosive rounds and zero scope sway when upgraded. I used the bow for most things though.
Never really touched the pistol or flamethrower during most of the game, and only picked up the Terror after I had done everything but the missions. After I realized that your guy screams after firing the Terror for a certain amount of time, I couldn't stop using it. Went through so many bullets.
Decided to try installing it on a smaller hard drive and it totally worked. Saw someone on the steam forums mention that it needs to be on a drive that is less than 2TB max, so I put it on a smaller drive.
Played for about two and a half hours, and the only issue I encountered was that the still-frame cutscenes lagged behind the audio until I turned PostFX (or whatever it is) to low. Other than that (and the pain to get it to work), it's played just fine, like Far Cry 3. I fucking love everything about it so far.
If they eventually put resetting the garrisons into the game, that would be amazing.
