You're not wrong, though I could counter that just a bit. For the handful of 'must kill to progress' segments I also let the A.I. handle a good amount of enemies, not because I had to, but because I wanted to stock pile as much ammo as I could. I finished the game beyond stacked however, enough that I could have probably unloaded on the few segments thrice over. Perhaps we both were just being a bit too cautious. What I loved most about Grounded was finding so many awesome routes that I otherwise wouldn't have taken the time to learn due to conservation not being dire.
