Ok, I finally got into this over the past week. Still om Ch. 3 because I got addicted to the Standard Deliveries. Getting 'S' Legend of Legends on almost every delivery. Also getting new weapons via story and via ranking up UCA Strands. I used to run from MULES. Now I run to them. BTs are still a little intimidating, but now that I have 2 or 3 options to combat them, it's not quite as intense. I also realized that Timefall doesn't damage the cargo even IF the container is ruined. That made it less intimidating.
I know Kojima has a tendency to let you think you have it all figured out -- right before he pulls the rug out from under you (and I know some intense encounters are coming since I was spoiled on a few things) but I'm finally getting comfortable. Couldn't care less about Sam currently but it's early. I'm sure he'll be fleshed out later on. I
am starting to see BB as more than a bizarre fetus. I put Sam to sleep while I finished up dinner. Heard laughter that sounded like my baby girl. Hit the corner and it was BB. I'm at a level 3 bond and I feel it. The progression from just finding BB weird to actually caring about BB's comfort level has been so natural and unforced that it's scary. Gotta tip my hat to Hideo for that, but I also gotta give him the finger, because I
know that was the plan and they're probably going to gut punch me later on.
